TLDR: there's " a game " here, not simply a VN. It has some drawings and some animations. But it's not fun. It's grindy and kills any kind of immersion. I tried this game around 2020, it's now 2026 and not much has changed in terms of immersion: there's a town, a school, cafeteria, flower shop and night club, and more... , but you can't do anything, except talk to characters and ask them for sex. You need to talk and flirt with them to improve your succubi skills to seduce for sex. That's it. Not details, small talks, reactions to your character. It throws immersion away and it also feels grindy most of the time.

"Book of Lust" is too ambitious and will never be finished. 5 years in development and it barely scratches the surface of what it promises (too many scenes/interactions variants - literally impossible te be ever delivered), and that's the biggest let down of this game: knowing it will never be a finished story. Overall it's a decent project and there are good things in here to enjoy, but its incomplete, too many things missing or half-done, and again, it will be forever an incomplete game.

seems deep and expansive until you realize half the mechanics either dont work or the scenes for them havent been drawn yet, might be good in a year or two. Real shame since this has the makings of a great sandbox, the author has just bit off more than they can chew.

This game is a wonderful experience, genuinely. There's just something about the game that just puts a smile on your face and its not even the sexual content. The world just feels overtly magical and exploring it and meeting its characters is genuinely fun. The semi-dark story honestly helps with this too as the struggles the characters are going through makes them feel so much more real than other games and makes you become somewhat attached to them. I came back to this game for the first time since 2020 and the music (which is incredible btw) and atmosphere had me genuinely nostalgic. Out of all the games on this site I can say honestly I feel that this is the best, and its the only one I would actually ever consider supporting so that should tell you a lot. By far it is the game I hope most is actually completed one day. With all that said though I have just one major personal gripe... *spoilers for those who haven't played yet* Caroline, Her personality and struggles really set her apart from any other character in the game. She is dependent on you and arguably holds you back, helping her isn't even in your best interest. And she knows this. That's what makes her special as a character, she is aware she does this and feels bad about this but at the same time she needs you. When all this culminates at the end of chapter 1 and you have to talk her down from the ledge of essentially (or actually) killing herself by showing her she is worth it to you, it is clear that these two characters have bonded fiercely and need each other. I found this to be really quite touching, then boom chapter 2 starts and you realize she isn't even living with you anymore and now is just Julia's shadow at all times. I don't necessarily mind the thruple resolution with her and Julia but any evidence of her bond with you is just completely gone. She never even seeks you out and even Julia visits you. By all accounts her and Julia are the couple now and you are just the side piece. It doesn't even make sense as these two barely even interact in chapter 1. The dev really built one of the most touching romances I've ever seen just to fuckin toss it in chapter 2. I don't get it. I would rater even have the option to cut ties with all of the other characters and just be loyal to Caroline than this. Chapter 2 has barely begun though so I am hoping there is still time to show that bond these two have again.

This game in theory should be perfect for my particular tastes, but it simply misses on a few crucial elements that bogs down the experience for me. The art is a 5/5 - in my personal opinion, this is one of the best looking furry games out there. It doesn't get too 'weird' with the art style, which is a major upside. Furry games often tie their art closely with their respective fetishes, which makes them very hit or miss, but due to the nature of mind control being a conceptual fetish more-so than a physical one, it feels less zany with its character's proportions. But since mind control is very conceptual, it requires proper context to work effectively in a game's story. If a game treats it as a mere 'sex button' - I lose interest quickly. And although I think BOL does a good job at diversifying the things you can do with a controlled character, it still feels rather shallow because it rarely has any contextual affect on the characters or world outside of the singular scenario, and I just find that boring. I can't squarely call it a bad game, because the art is great and there is a lot of it, but it never delves too deeply into each character's psyche regarding the effect the control has on them. And eventually it sorta does become yet another 'sex button' game, just with a few extra steps.

Honestly, I just wish more of this game was based around consequences for character actions. Like, the art is good, the gameplay is good, the balance between reading and player choices is good, but it would be nice if the characters would have some kind of panic or something when you switch out of them and they see that they are pregnant or did a bunch of things without having control over themselves. Since the description on the front page is a little lackluster, the full detail of the game is that you (male MC) get a succubus as your new best friend and she lets you use her spells to do things like let you possess people, have her possess people (like your mom), make people horny, and so on. There is pregnancy as a mechanic, but it's a magical pseudo pregnancy that the characters give birth to overnight and it really doesn't have much bearing on how the game plays out, but it does alter some interactions and sex scenes.

Lem-Maelstrom 2024-10-18 ★ ★ ★ ★ ★

This is a long review because typing is fun and I'm bored. Kanashiipanda's art style is unique, and very good. The animated parts flow nicely, and the still frames are very very good. You can justify the entire game on the art. Even the non-erotic art is good. Beyond that, the game has a great soundtrack I would unironically listen to in my free time. I'm particularly fond of the tracks "Memetics" and "Not a happy bunny". Consistently updated, with a lot of content. If you have a non-violent fetish, this more than likely caters to it, and if there are fetishes you dislike, you can mostly avoid them because almost all of the lewd content is player-choice related. You do have to use the lewd content to progress your abilities and the story, but the point I'm making is that you have a lot of options and you get to pick 90% of the time. If you tried hard enough, I'm sure you could beat the game solely through consensual sex with Succubus and Caroline if you were so inclined. ++ Character Review ++ (Character and Story Spoilers Ahead) Jake : Jake is the POV character with a very silent protagonist name, but he does actually have personality. He's a very, very rare self-serious erotica protagonist, and I enjoy how gravely he approaches most of the plot. After all, the plot of this game is pretty dark, and I'm glad he's not wise-cracking or whining his way through it. His character is a fine-looking default wolf guy, which is okay with me. Succubus : She has a name, I'm almost certain, but she's called succubus for most of the game so that's what I'm going with. She's a central part of the plot, and has her moments to be funny or serious. She does a good job in the job she is given, which is to be exposition woman. As she is not really a person, she has no art, but I do enjoy the way other characters change when she possesses them, from the eyes to the pose. The plot twist of the Succubus being who she ends up being was super out of left field, but surprisingly good once it settled. A little more foreshadowing would have been nice. Even if it's just a picture frame you can click on that has Jake say something. Olivia : Protagonists mom, and a profoundly strangely written character, because she's depicted in some areas as a very doting, easily flustered mother with a teasing side, and in other areas of the game she's a relentless pervert who laughs at the notion of propriety. I personally enjoyed the innocent side of her better, as she seemed a lot more realistic and a lot more fun to talk to, but I guess if we want to interpret her as "layered" instead of inconsistent, it can be forgiven, and all that forgiveness comes from her character design. She's on the cover of the game for a reason. Cassandra : She's a typical older-sister type who has an appealing design but not much else going on. Her relationship with Mel is easily her most interesting trait, and that's not really a compliment. Caroline : Your sidekick for part I and one of the better written characters until very suddenly shifting personalities from self-doubting, dependent, hopeless, and frantic to extremely self-sufficient and slutty. Up until that stark point (it is addressed in the plot, but one or two acts of dominant sex does not justify the change to me) her dialogue is easily the saddest and most interesting of all the characters, by a wide, wide margin, and her arc resolution is great, I just think the aftermath was way too much. Her design is good too. Julia : The POV character's established girlfriend, Julia feels like the weird hybrid of a band geek and a cheerleader, and it works. She's also one of the overtly slutty characters where it makes sense and doesn't conflict with another established trait. At first I dismissed her as a bit shallow, but she's got a few great lines hidden in there, especially during the whole body-swapping part. I think it's funny that the protagonist was also surprised that she had more depth than meets the eye, as he comments that he had no idea she actually put a lot of thought into her actions. Her design is great too. Mia : Julia's mom, and a complete tangent of a character. You can beat the game without so much as speaking to her. If you bother to pursue her, you get some weird but interesting sex scenes that raise of lot of questions the game should probably leave unanswered. Donovan : Julia's father, equally as unimportant as Mia, but unlike Mia, his presence makes the story worse. See, Mia and Donovan are both adulterers, and both sleep with Olivia, among others. The amount that they do not interact with one another, and the amount that Mia interacts with the player and others, makes Donovan's presence relegated exclusively to satisfying an adultery fetish. He simply does not exist as his own character, at least right now as of the update I played. I think Mia's character, and her relationship with Olivia/the player, would both be substantially more interesting if Donovan didn't exist, or died at some point. Yeah that would defeat the fetish, but it would also give the story with Mia a lot more room for depth, which would be worth it. Mel : Cassandra's boyfriend, Mel exists to fulfill masculine stereotypes, and to the end he does a great job. He is in every way what a shut-in geek thinks an alpha male looks like, and in a visual novel type game, that's fine. He could use either a bit more humor or more backstory in my opinion, as he takes himself as seriously as Jake, but far as I can tell he has nothing going on to merit that seriousness. His design is the most mediocre of the cast. Also he has a weird thing for his girlfriend's mom. Fidelity really means nothing in this universe. Valerie: I think she's a mule? I also think she's semi related to Mel, but I'm not sure. Either way, she's an interesting character with a more unique design than most of the cast can boast, but unfortunately, I paid little attention to her side-story. What I have seen was pretty good, but I really can't say more. Like Mia, she's not really involved in the story unless you go out of your way to involve her, but I think that's changing in part II. We'll see. Every Supernatural Character Besides Succubus : Horny and not that interesting. A few also don't really mesh with the art direction. I feel bad being so general, especially with how much attention characters like the Raven Mother and others get in the story and out-of-universe artwork, but I really have nothing nice to say, and even less constructive to say. They are what they are, and it's... fine... I guess... Easily the least compelling characters, and least appealing to look like. If I have to say something meaningful, it's that G'nisi proves this art style does not mesh well with scalies. Maybe it could with a redesign, but I'm not sure. + Gripes + (Big spoilers. Also some of this is just personal taste) Having no choice but to share your girlfriend with Caroline after ACT I to become a thrupple is not a great resolution for a host of reasons. I like Caroline, and I like Julia, but I would much rather have had the choice to pick one over the other when the bell tolls. I think the reason this outcome feels not-wonderful for me specifically is because I barely even saw Julia during my first runs (as she is mostly optional for ACT I), so it felt very strange when the character you spent the whole game with up until that point basically becomes attached to a DIFFERENT character. But even if you didn't have that issue, it seems like a not-great resolution. If you were really keen on Caroline as a romantic partner, I can see this being very annoying because now she's with someone else. If you were really into Julia as a romantic partner, I can see this being SUPER annoying, because now you have to share your girlfriend. I don't mind the thrupple resolution, and I wouldn't mind a harem resolution if the author absolutely must keep both romances open simultaneously, but I'd at least like the option to pick one or the other as well. That would make my opinion of act I's arcs go from 8/10 to 10/10. Gripe numero dose: Donovan should die or something. That's probably just me (I'm almost certain it's just me), but I really think Mia would be a much, much more interesting side character (and a much less morally dubious one, but that doesn't really matter to my point) if Donovan perished, or better yet, died in the same attack that killed Jake's dad. Considering the grand sum of Donovan's in-universe participation includes about five lines of very mundane "hey how are you Jake" dialogue and one scene of him cheating with Olivia, his lack of existence would take away nothing, and let the space he wastes be filled with something much more interesting for characters that have a personality (Like Mia). Every adult character and every male character that exists, Olivia is canonically engaged in sexual/romantic relations with. I find that silly and weird. This is more a nitpick and a "haha look that's funny" than anything I actually want to change. Other than that, the writing is solid for an erotica game. Solid as in it works, as over the many hours of playing the game only two or three conversations ever struck me as deep. + FINAL THOUGHTS + It's worth playing, and hey hey, worth the money if you're that kind of person. I'd personally change quite a few minor story elements, and tweak about two character designs (and remove Donovan), but otherwise it's enjoyable from front to back, and it's not a short journey.

Putting this review fully based off of facts The art is AMAZING, the gameplay is long and entertaining and the characters are perfect. I have some personal opinions but they really don't matter when this game is a pretty awesome game with good updates, great art, and some actually good scenes that branch out.

I found "Book of Lust" a couple years ago and have been following its updates ever since. The game has a cool storyline with rich lore that pulls you into the adventure. Each character is unique, with their own backstory and personality, making the interactions really interesting. The animation is awesome. The characters move smoothly and expressively. The attention to detail is great, and it kept me really excited and happy throughout the game. What I loved the most is the amount of space for interactions. There are so many ways to interact with the characters, which makes the game feel fresh and exciting even though the main plot stays the same. This is a great mix of story and scenes.

The game has a lot to love with many character interactions. The amount of combinations with body swapping + possession + impreg content is impressive. On top of that hand-drawn animated scenes? Just a delight, and it touches on a lot of flavors that I enjoy. The same quirks that make BoL great, are what unfortunately will leave it in a perpetual development cycle. There are 15 characters in the stat sheet at the time of writing, so that would be 210 scenes from each perspective for just body swapping (ignoring variants). The multiplicative scene problem the dev is creating is similar to the impossible hamster . With each added character the amount of variants grows out of control. My advice for KanashiiPanda is to separate out the kinetic novel chapter part of the game with the sandbox part.. Have new characters as part of the linear chapter side story but LEAVE THEM OUT OF THE SPELL BOOK. Right now the new player experience is: After leaving the Hart household and using the spell book to be met with black screen after black screen with placeholder text because the scenes will never be finished. It's impossible to expect the dev to hand draw all the variants. Game needs serious fat trimming, focus on the Hart household with at most 4 characters total for example Cassandra, Jake, Mel, Olivia with full scene variants using the spell book, because to me the bright spot of the game is the use of the spell book to achieve wonderful scene variants, which keeps me coming back from time to time.

For a vn style game, it actually has a lot of interactions. and i hate VNs for how boring they usually are. this one is definetly better though it's got a bunch of WIP content. The grind for exp is a little bit tedious, but it could get adjusted or there will be more opportunities with new content. As for the art style - it is simple yet it's not bad. i hope i will be able to bump it up to 5 whenever it releases

Ok first thing first this game should not be considered a VN. It is a sandbox and it should be clearly tagged as it. Even though I had inferred it been a sandbox by reading some of the reviews and the guide, it was worse than what I expected. If you like sandboxes give this game a real opportunity. The game looks amazing and I enjoyed the few scenes that I managed to achieve before giving up due to its sandbox nature. This game has all the traits that people love about sandboxes and I personally dislike. You need to grind stats; you have to wait for the perfect moment in time to reveal some scenes; you have “freedom” which for me translates in being lost and not knowing exactly how or where to continue. I rather read a straight story line with some side stories than having to look around and complete side quest to be able to advance other quests or the main story. Anyhow, congrats dev If you make this game into an actual VN in the future I would love to play it and I am sure I would thoroughly enjoy it.

I'm totally into the game's concept, it's really nice how you can switch bodies with almost anything. I really hope it gets the spotlight it deserves! One of my favorite games. Can't wait till the next update

ironnara 2024-01-10 ★ ★ ★ ★ ★

Really enjoyed this game! A good amount of content so far and a good range of interactions. Love the possible combinations available from the possession/body swap abilities and hope to see it expanded further.

Not into furry but this checks the prego fetish box so here we are. Now lets get started on the loop its simple the usual have sex with xyz and keep doing it go to sleep get some exp as you do things and level up your spell book. Get characters to max influence/ love have sex sex sex. It does have a small story to get the ball rolling but ya know this be a sex game that is still in dev since the dinosaurs went extinct. There is still a crazy amount of unfinished art that i remember seeing not finished from many moons ago probably years? All in all its ok better the most of the porn games but no where an top of the food chain. If you got time to kill play it if your impatient it has a cheat menu and you can just skip through content to see the scenes quicker.

PDP19 2024-01-03 ★ ★ ★ ★ ★

Just to give my own take on the game thus far. Its incomplete, so I may come back and revise my review from time to time. PROS - For a VN, this game is surprisingly complex. There is a coherent reason why you have a spell tree, why spells are necessary at all, and youre not just moving from one sex scene to another - There are animated H scenes, so its not just a pic waving about as you hump - Story is fine, fairly well told. Not great or anything, but I knew what was going on and what my character is supposed to be doing, with some allowances made. - The dialogue doesnt cheese me off, which is always a plus. Usually VN dialogue not only pours 2nd hand embarrassment onto me, Im usually very quick on the skip buttons. This one though, while dialogue is completely skippable, Ive rarely used it. CONS - Music is bad. In fact, there's either a bug thats turning off the music from time to time, or the dev is keenly aware of the subpar music being used in this game. - The game's complexity is all tied to sex, so it shouldnt be surprising that youre doing it, ALOT. There's such a thing called moderation, but this game clearly ran through it with a spike. There's only so much sex a man can take before concluding that something is wrong in the air. - There's no VA for the H scenes, which is always a disadvantage no matter how well made it is. - Artwork is perhaps only charitably described as decent. Alright, here's a short summary of the story, without spoilers. You play as Jake, a normal wolf of college going age. One day you accidentally released a succubus from a sealed book which you got as a birthday present, and that demon possessed your mother. You then proceed to have sex with your mom (following me so far?). The demon explains that she'll only release your mom if you can figure out how from the book and to do that, you'll need to essentially be fucking a lot of women. Ok, that's the plot. At least youre not some crazy japanese hero fucking what clearly is an eight year old. Gameplay is fine up to a point. There's not really much else to say other than fuck ladies to get exp, which will allow you to get spells so you can fuck even more ladies. At some point you'll be able to swap bodies so you can fuck all of them again and sometimes even their male partners. With regards to the artwork, well...its kinda mixed because the bodies are drawn up to par, I cannot easily spot mistakes on proportions etc. and yet the head and faces are so below average you cant help but feel that the artist is deliberately drawing it shite just to fit into what can be generously described as a 'style'. So in conclusion. All in all the story is fine, the dialogue doesnt grate, and the game is not just a linear spacebar adventure. Unfortunately, Im not a fan of the artwork and presently thats the only real problem I have with the game. Feels like eating nutritional pills rather than a hearty meal for dinner. I can only recommend it because at the end, theres really not alot of furry niche VN in the market, with competant stories and artwork. You can have pig princess which is sublime in artwork yet shallow as fuck, or you can have this, a well paced, complex gameplay VN experience, but with artwork that flatters to deceive.

Book of Lust, a visual a furry novel with lots potential, the game promises an enthralling experience from the very beginning. The art style and atmospheric soundtrack further enhance the allure. Regrettably, this enchanting journey is tarnished by the overwhelming sense of incompleteness that pervades the game. Key elements, critical scenes, and character arcs are conspicuously absent, leaving players feeling unfulfilled and yearning for more. The lack of polished content dampens the impact of the narrative, leaving Book of Lust a fragmented tale. One glaring issue is the absence of visual cues or guides to help players navigate their way through the game. Without a clear indication of what to do next, players can easily become disoriented and miss out on crucial content. The lack of a coherent flow disrupts the immersion, leading to a sense of frustration and confusion. Moreover, missed opportunities to explore the world further. The potential for deep interactions and meaningful choices goes untapped, leaving players with a lingering feeling of missed opportunities and untold stories. For this vn to reach its full potential, a dedicated effort to finish the game and implement visual guides is essential. Only then can players fully immerse themselves. Despite its current limitations, Book of Lust manages to tease players with what could have been a remarkable journey into a realm of temptation and passion. With the necessary improvements, this visual novel has the potential to captivate and satiate players' desires for an unforgettable and complete experience.

i think BoL might be the most above-average h-game i've ever played. its strengths are good but not remarkable, and while i enjoyed the game as a whole, it could use a layer of polish. the art style is the most glaring example of the whole "polish" complaint. it reminds me of old newgrounds flashes: simplistic, mostly unshaded, and cartoony. this style works great for the (many) animated scenes, but it can come off as flat elsewhere. now, frame-by-frame animation is, to put it lightly, a massive pain in the ass, so i understand why the art be like that, though i can't help but feel like it could use a little love in places. on the flip side of that, the actual love part of the game is its biggest strength. i'm glad for that, because sex magic is a great selling point: it helps bypass the traditional VN relationship stats grind, and most of the supporting cast has at least one bonus scene that you can only access via mind control, possession, or other, more subtle tricks. a brief aside: while the spell system is a great concept, it means the amount of scenes an artist needs to draw scales out of control very quickly for each character. body swapping, mind control, possession, suggestion, magical impregnation, etc. all would require their own scenes for each spell beyond vanilla sex. with hand-drawn art, this is problematic. with frame-by-frame hand-animated art, this is next to impossible for a solo developer to achieve within their lifetime. if it killed Breeding Season, it could kill BoL. as far as the aforementioned supporting cast, most of them feel like they could use some fleshing out, but the few who play their parts in the game's questlines are great. their emotional beats work, their backstories and lore are well-conceived, and they're generally likeable. it's promising writing all told: Kanashii, if you're reading this, read more books and write more stuff! you're one of those talented writers who grasps the foundations of good writing; all you really need to become an excellent writer at this point is practice, patience, and time. and also a proofreader. everyone needs a proofreader.

v0.0.79.1b I have been following this game for years now and it really isn't going anywhere. The game has very good looking art, and some of it is even animated. It is your typical succubus contract story where you mindfuck then normal fuck your mom, sister, and then a bunch of other girls. As a twist you have a bunch of different spells you can cast, also furry. You have the standard mind altering ones, but also more exotic ones such as sharing sensation. The pregnancy content is very very disappointing. You cast a spell to create create a magical familiar then "impregnate" a woman with it. after super rapid pregnancy she gives birth. the familiar then fucks one of the women in the game all night to harvest sexual XP. then it happily "merges" with you. basically killing it to give you XP. and it calls you father too which is very disconcerning. It feels like offscreen vore of potentionally your monster child. Also NTR because your son just fucked your waifu. What really trips this game up though is the possession spell. At the start of the game you are basically made into a demonic copy of yourself possessing yourself. There is still the original self in the body, and if you body hop then it will reassert itself. But you are a new entity with the memories and personality of the original that can possess any NPC, male or female, in the game. Math fun-time O'clock! X = number of love interests in the game If the MC never engages in threesomes and never watches NTR then the number of possible pairings in the game is simply X. If X is 2 you need to make sex scenes for 2 pairings, if X is 20 then you need 20 pairings. If you want a dozen scenes per love interest that means you need to animate 12X scenes. For 20 waifus that is 240 scenes that need to be animated. Now add the possession spell. The formula for this is... (X+1)*X. The +1 comes from the fact that the MC is also a waifu. And that A fucking B != B fucking A. So if you have 20 waifus that is 420 possible pairings for vanilla 1 on 1 sex. a dozen scenes each and you are looking at 5040 scenes needing to be animated. But wait, there is more! You can use a spell to change who the succubus possesses, and you can order the succubus to switch between full possession and subconscious possession. These all alter the sex scenes. Meaning you need to triple the figure from before. so instead of 5040 you need 15120 scenes! Then throw in some extra scenes for familiars, 3somes, NTR, and so on. This gets worse with every waifu added to the game. The possession spell changes the number of scenes needed per LI from linear growth to quadratic growth, and the succubus triples that. The author simply set an impossible goal to himself and this game will always feel very threadbare, because he does not focus his effort on completing the route of a single MC. Instead all possible MCs are getting attention. Now, he isn't exactly spreading it around equally. There is still a decent-ish amount of content for the original male MC. But all those other possible routes are a mere distraction. And you really must have a guide to find what content is available. However there is no such a guide, you have to try all possible combinations manually. And they all require grinding before you can try anything, and then once you grinded you usually get a WIP scene instead of an actual content scene. I have zero interest in playing as a female MC and I am not into self cuckoldry so I will not be changing who the male MC is via possession spell. I am also not gay so I will avoid the male love interests, and have no interest in NTR... This is a pretty standard mindset in my opinion. and cuts down the vast majority of combinations, meaning a lot of updates contain nothing of interest to me. But even if I was into all content this game puts out it would forever be a huge morass of WIP scenes because it is literally impossible for the author to ever make a meaningful dent in this game's backlog of scenes. It might be worthwhile to waste a couple of hours on the starting MC though. Which is why I am still giving it a 3/5 instead of something lower. But don't expect this to ever be anything more than a ton of WIP signs.
