Excellent H-mode, so-so independent CGS It's a slow game with an exponetial growth for the development and bond building. The gameplay animations are genuinely very good, and plus the little text box with descriptions is really neat! It really adds a lot of spice to the gameplay

I don't even know why I played this bullshit. All that grinding for a bunch of terrible CG's. I get so frustrated when games waste my time like this. This game is a great example of that average score doesn't mean SHIT in this site. I'm really wondering why ANYONE would give this more than 1 maybe 2 stars out of 5. What a disgrace.

Just another unity [run away girl so now you look after her sexual fantasy] type game. Game play is easy. There's no strategy for the deadline. As long as you spend some time attacking. That is literally it. Not a management game as you don't even need to think what to do. Music is cool. Art is nice. Story is...it's a story Perfectly average type of game. Play if you want to see some live2d physics.

Do not get me wrong from the 2 stars [EDIT: 3 stars now], the proper content in this game is quite good. But there's just so little of it and it's stretched so thin to give this game many total hours of "gameplay" that the end result is the game is mostly boring tedium. This feels more like a prototype rather than an actual game. There's the dress-up system which lets you choose what the girl wears (there's not really any other characters besides her and the PC/MC), and she looks great in all the combinations. She also wears the chosen clothes in her one animated interactive sex scene, which works great also from the animation perspective. The art is quite nice throughout. All this is the core of the game, that and the quite fun outlandish conceit behind the story and the girl herself. But that's just... not a lot. Over that are stretched systems so simple and barebones it might as well be a VN, except it's a VN made up of just small vignettes where just 2 characters interact, and the vignettes are interspaced with watching always the same short animation on a loop for a bunch of minutes. I don't care how good that animation is, this does get old and it does get old quick. It's a shame. Were it not so dedicated to wasting time, it would be a fun light game with a weirdly cute light story (for one where literally everyone on Earth might die and even if they don't destruction absolutely has to be rained on the unwitting innocents en masse). As is, there's that interactive sex scene I mentioned earlier. You unlock it and most of the interactions in it right after the intro, and unless you have a specific reason it's not really worth it to delve into the game further than that. The cost in time wasted is too great. EDIT: I gave the game another shot. Not that long after writing the review, I unlocked an ability which then accelerated my relationship points growth in the sex scene more than tenfold, so I could just get 50k and then not have to touch it again. This changes my estimate of how much time you have to spend/waste in it a ton, so 1 more star. Weird that they'd make their best scene such an anchor dragging the game down, but it is what it is.

The game come with pretty outlandish premise, basically cohabitation with heist operator. As cohabitation, it felt lacking, all the heroine got going for her is her face and body, with no personality or goal there's almost nothing remotely endearing about her, how do you felt living with crypto miner as your roommate? As porn, well I hope you're used to play MMORPG or Active commenter on Stream, because any semblance of teaching the heroine pleasure is written like auto erasing chat log. The scene itself is well animated, it just felt not personal, the best way to describe it is like: Hiring a hooker on missionaries position, but instead of moan and gasp, she fiddle with her phone while you shout "Yeah!, Feel that?!, Conceive my seed's, Bitch !"

Story: "Teach a monster how to be human" While that sounds cool in concept it's not actually some beautiful and ssoulful story about the human experience and emotion, just detailed enough to qualify for that moniker and satisfy the emotionless sex crowd. It's all a giant justification for the game's premise, even as it ends that never changes, though you're unlikely to notice or pay attention to such considering most people's hands would be on their cocks, so no worries for anyone I guess. Gameplay: "Gameplay" would likely be a stretch, I know some people believe that as long as porn games fulfil their primary function, that is being a porn game. Gameplay, or lack therof, is not necessary, as long as it isn't tedious and can be played with one hand is enough for some people. I'm not of the same opinion however, I can't sit through clicking simulators whose only reward is some sex. All in all, it's a visual novel with gameplay elements than it is an actual game. Art/Design/Animation: Kp 1 still has the best art style despite being the first game. It's cute, vibrant, sleek, and colorful. Though this game has less things to design by default my opinion remains the same, altough I wish the outfit creativity was better. Sexual content: While the idea of teaching an unfeeling monster who knows not of pleasure, pleasure, is good. Due to the lacking positions and outfits plus any sort of atmosphere that could enhance the experiencee, for me this is very mediocre sexual content. I can objectively say that this is better than most games in its quality due to voice and animation quality, but my opinion will remain unchanged despite that. Sound/Voice Acting: Likely the "worst" out of all the games due to how much of a boring role Xan is. It's not as if the VA did a bad job, like how writers can ruin an actors performance so can they ruin a VA's performance. I guess atleast it has Va? Like always, porn game sound design is non existant, not good enough to be noticed not bad enough to be a problem Final thoughts: An alright experience if your really have the time, but i'd recommend putting this on your bookmarks and playing something better. Rating as a porn game: 3/5 Rating as a standard game: 1/5

What a boredom, when I played this game my face expression was no different from the girl's one - she looked bored no matter what. Game mechanics is poor, everything is predictable, the girl is boring and meh, what is the point? Right, there isn't.

This is a cute little game that I highly recommend you play if you enjoy VNs with some management elements. Plot: The plot is fairly basic but it has it's charm and overall the pacing is good. To sum it up you help the Kaiju Girl meet her terror quota so you can continue living together. Over time you both grow more affectionate until the last dead line arrives and you guys get some time off CGs: Now what you all are actually here for, the cgs are very well drawn and none of them look off or anything. Some of the best I've seen in terms of quality. Gameplay: It's very basic with you managing your apartments cleanliness as well as the Kaiju Girl's hunger, affection, and mood. Going back to the quota from before you have to attack towns and whatnot to increase the amount of terror harvested. After a while you become "familiar" with some of the locations which unlocks new outfits and cgs. My only complaint is it will get repetitive after a while but the stuff in-between helps a lot. Length: I'd say 5~ hours but that's a rough estimate. Music: Not something I usually rate in games like this but the music is lovely and doesn't get old. TLDR: Decent plot, great CGs, and kind of repetitive but fun gameplay

it is hard for me to rate this fairly since i played the newest game first but i will try to be impartial. 1. Good art: this is already enough to make many people like me play the game. 2. too litle animation: it only has one animation that is the interactive one, it has some good cg but 2 or 3 animations would be good,it is the reason why i'm not giving this a 5 star. 3. cute story: to be honest the story isn't my cup of tea but i'm not gonna judge for that since i didn't read everything but i know the general direction and it is nice to see their relationship getting better since she start as a really cold girl

First of all, I'm sorry that my English is not good enough I really liked the fresh story progress like my first love. The CG and voice acting were great, but I think the most perfect part is the BGM. I think the high-quality BGM melted well into illustrations and stories, and showed beautiful harmony. However, the overall lack of content is serious. I heard that the follow-up will be released in December this year I hope to meet you again with a more mature work. Anyway, Well-made game. 8.5 / 10 - Koichi Morita - Shining Star (Kaiju Princess Ending Theme)

A very inoffensive game. I question Those who complain about the grind as yes while there's one scene it never acts like there's much of a chase. She's no real different to a sex doll outside of a small growth in emotion throughout. The difference between hour 2 and hour 12 is her expression and a few optional non animated CGs. Otherwise you're just fine doing the scene and calling it a day. My issue mainly comes in how little there is to manage. Cause damage for quota, buy stat improving items and go to work if for some reason Kaiju battles don't give you enough money, clean your room, feed the doll every other day if you reach your quota. Do that until you run out of shit to buy, reach quota and then bang her for the remaining days you will quickly run out of content before the end. a game that sets out what it wants to do but at the cost of anything interesting
Borkeddown 2024-03-04
Fairly repetitive and lackluster. It's a good thing they decided to give lazy sex girl a monster hoodie and tacked on a kaiju plot, because titles like Missionary Position Simulator just won't hack it these days.
Soda_so_dna 2024-03-03
Boring farm, minimum variety, stupid plot (I just missed 10 days in the end, and the heroine was worried that "I'm putting too much effort" - yes, I put a lot of effort not to fall asleep!) Monotonous animations, minimal variability, annoying "new" notifications in the gallery, despite the fact that you just watched it! The whole reward for tons of pharma is the same little scenes in the gallery. There is no development of interaction. And, for some reason, some "achievements" do not open, however, they are also of no use, because well, you can salt the coitus scene a little longer, but of the new interactions, only toys from the store that open during the course of the plot. I DO NOT RECOMMEND THIS BORING STUFF AS MUCH AS POSSIBLE! HOW I HATE MY PERFECTIONISM!

10/10 would forsake humanity again. Seriously though if you like games like runaway girl, or imouto life seriously we need a tag for these types of games where you can control the sex scene like choosing which part to focus on and what to use, if youve played those games you get what i mean when i say control the sex scene anyway back on track, you Train/help/work a single girl to upgrade her stats and or love and this one has the gimmick of kaijus. anyway the Female Protag is extremely likeable (also extremely relatable) and its a nice game i would recommend to waste a day on.

I didnt expect there to be so much grinding. I think also overgrinded because i didnt know what the max relationship points were to get all the scenes. I went all the way up to 70k relationship points, but i got no new scenes after 40k. I wish there were more animation sex scenes, but there is only 1 position that you have to grind out the entire game. I dont want to give this a bad rating because the art and story is pretty good, I just dont like the grinding. I also wished the voice actress would voice more lines. Overall, the gameplay is kind of mindless with no real challenge, but story is unique and the kudere princess is quite cute, so it was a good game.

Overall 4/5, a pleasant "girlfriend experience" game, management gameplay is basic but enjoyable, story is "feel good" and executed quite well. Gameplay 3.5/5 going through days with some basic management, its enjoyable and doesn't get too grindy Character 4/5 a usual character with a simple story that is well done Other things to note, though the game is not grindy, the H scenes are. also it definitely does not meet expectations if you consider the really high ratings on steam
len00 2023-07-26
From the Steam 97% positive reviews and the 4.5/5 here I expected the game to be something more, the game is cute but pretty basic there's like 5 sex scenes and 1 animated position u can do every night, I usually don't like games that overload on porn either but this game has too low content, the story doesn't try to take any interesting turn and just goes along with the most basic scenarios, maybe if it has a part 2 it could get interesting but for now, low on content compared with the hype it has.

Overall a good game. The art style is excellent and the game is of very high quality. The character design is great, the girl is really cute and the art quality is amazing. It is also animated which is another big plus. The art quality in general is amazing and this is a very well polished game. The most depraved part is that there is a bit of sleep sex which is good, otherwise it is a fairly tame/vanilla game. The actual sex scenes are decent, the art and animation is amazing, though it does get a bit repetitive. There is only really one interactive scene and the rest are CGs. I dont really mind this too much but it would be nice to have some other positions to interact with the girl. Some other things include that the game is a bit confusing at times in what I should be doing. A notable good thing about this game is taht there is some voice acting which adds to the game and is great. Overall a very well-polished game that is pretty chill to play. A-tier game, 8.3/10
Burnt Origami 2023-06-20
Kaiju Princess is a simple premise that delivers in interesting ways, but does not blow anything out of the water. Though a bit grindy at times, it is fun and not too difficult and provides some juicy lewdness. In its corner of the industry, this is a star in my opinion. Read on for more details. Story and Gameplay Your friend has convinced you to join a website where you offer shelter, food, and care to women in exchange for... services. Your first (and only) client is an odd woman who seems disinterested in just about everything, but understands the terms of the deal. You take in Xao, and shenanigans ensue from there. The gameplay is a simple manager. Don't let your room get dirty, feed Xao, go to work, talk with her. Eventually, you will realize there is more than meets the eye to her situation, and now you must also manage attacking cities by selecting where to attack and when to prevent ultimate disaster and eventually game over, should you fail to meet quotas by a deadline. There is nothing too special, and it is simple enough to get the hang of things and get in a rhythm, meaning I never felt close to failing (if you do, the game gives you the option to recover). The gameplay itself can get a little grindy (more on that later). Controls are about what you expect from visual novel/manager. There are some times where it seems like skipping can be a bit slower than I like, and for some reason hitting spacebar does not advance text, but can sometimes trigger the same button you just clicked again, causing me to accidentally perform the same action twice. The auto button and skip button also do not stay on. The Sexy Stuff Right from the get-go, you have the option to engage in the act of sexual intercourse with her, but don't expect great results at first. This game is about the slow-burn, building a relationship, and enjoying the goofy antics along the way. That being said, as things advance there are some scripted "cutscenes" that add some new flavors and the sex gets a lot better as your connection with Xao develops. You can unlock some daily activities such as kissing, head pats, and face rubs (so extreme!). Outfits are cute and can be mixed and matched to create your ultimate sexy lazy, sexable waifu. By the end, you will be controlling the ways you deliver her pleasure (though her responses are vocal moans and written writing). However, these are pretty much limited to missionary position and activities. If you want others, some of the scripted novel-like scenes can probably fit your flavor. Still a great time for my mouse hand and other hand. Art and Sound This novel/game uses the live 2D style of art that is really good. The girl is cute in all her outfits, the expressions are funny, and sexy times are great. The backgrounds are not the focus of the game, so I don't mind their relative simplicity. The animations during gameplay are greast too. The voice-acting is sparse, mostly just short phrases in Japanese or Chinese during dialogue (except towards the end). The H-Scenes are voiced as well, but mostly driven by text. The music is an earworm. Simple and though slightly repetitive it doesn't get old. Nice enough for this type of game. My Notable Highlights Good gameplay that is not too grindy Good development of character relationship, unlocking new and funny dialogue Sexy times are nice too Can be finished in a few hours if you stick to it, but can be fun to take longer on Outfits and most scripted scenes are easy enough to get Potential Flaws The H-Scenes can actually be the most repetitive part of the game, and considering they are a highlight of the game, it is a bit of a shame. The text does not have much variety, nor do her moans. What it lacks in variety, it suplements in quality but it can get old if you tried to play the whole game through in one session. Though the majority of scenes are easy enough to get, some require some really outlandish progres on the relationship. For this, I would recommend the mod in this forum to speed up the rate at which you get things. If you like the developing dialogue, be sure to try the different interactions at each stage to hear Xao's responses. Some grinding of sex is required to get better at sex. Realistic, but maybe not what everyone wants out of the game. The game cannot really be lost, as it offers you the ability to give up completely or retry with current progress kept. If you care about challenge, there isn't too much here. My Conclusions This game is good, for what you are expecting. If the grinding makes it unappealing to you, spin up the mod in the forum to have some nice sexy time. However, I recommend the story, the character development, and charming humor to be experienced at least until the end of the main game to have the satisfaction of helping out another person and teaching them the joys of humanity. That's what this game ultimately comes down to: a love-letter to the joys and strangeness of human relationships, from the lewdest head patting to the raunchiest sexcapade.

Kaiju Princess [v1.09] [PantyParrot] I love drawings, she's cute, and I've always loved games with a structure like this. Excellent graphics, nice dialogues, gameplay that works even if too repetitive, very nice clothes but with very few functions and therefore practically useless. I recommend the game despite being very basic, which makes everything really too repetitive, the night phase becomes nauseating after a while.
