I originally planned to release this earlier in the week, but I decided to take some extra time to refine the new features before putting it out into the wild. Version 0.0.3a was primarily meant to be a bugfix build, but since I was in the middle of adding new mechanics, it now includes several new features: Difficulty Settings Save Slots Autosaves Subtitles (enabled by default) The first three were discussed in the last Dev Log, but subtitles are a new addition. These apply to non-dialogue voice lines, meaning hit reactions and miscellaneous vocal cues now have associated text. Bug Fixes: Fixed a bug where dying in a boss fight would send players back to the main menu. Enemies now react to being hit. The main quest now progresses correctly after defeating the Duchess (Failsafe added). Balance Adjustments: I’ve also buffed melee weapons and made a change to parry mechanics – enemies staggered by a parry will now take double damage until they recover. Both of these changes might make the game too easy, so I may tweak it later. As always, feedback is welcome and best delivered on the Discord server. Unless any major bugs pop up, the next release will be 0.0.4, which will hopefully introduce the next dungeon. Until then, enjoy the update! Known Issues: The player sometimes snaps back to their previous position at the end of a sex scene. Controller support does not work in the Map or the new Extras menu. Enemies may stand around during a sex scene – or sometimes spin for no reason. The Stalker Timer sometimes continues after changing floors. Stalkers may freeze when you start hiding. Audio levels for voices are inconsistent. Dying to a Stalker can result in money bag being dropped in the void. Statues are buggy. v0.03 N/A v0.02 N/A

Another actual " game" around here. The experience was pretty enjoyable. The start was quite strong, but later on, the terror died down a little due to you becoming a bit too unkillable. Got a bit of everything, there are optional quests, levelling, perks, and even boss fights. Though I'm still confused about the purpose of the sanity bar, if the consequence of neglecting it is so minor.

I finished everything in 6.8 hours according to Steam's playtime tracker. It's got cool monsters. Only a few at most are body horror, the rest are humanoid with some extra trait (like being a ghost, having a creepy mouth, etc). Personally I wish there were more freaky and crazy things. My favorite was the Spoiler Darkwood splitterhead enemies in the straightjackets. Just a cool monster design in general, and then in the sex scenes the way they animated the heads jittering in the orgasm animation, plus the SFX, plus the like strings of juices between the teeth, I thought it was excellent. Besides that pretty much everything in the first dungeon were the runner-up best monsters. Story and writing are good with a big exception for the dialogue, which I thought was extremely rough. Music was good when it was there, but when you're dungeon crawling no music plays, it's totally silent. Really big miss imo, I wound up trying to put on my own background music. The gameplay was okay. It had many problems but felt novel. Ultimately it was sometimes tedious to the point that I put on a stream on another monitor while playing just to try to curb the boredom (like, you have to do later dungeons 4 times in a row before moving on, which felt like plain and simple playtime padding. By the time I did a dungeon twice, I was very ready to move on). I played on Easy because Normal difficulty was killing me and was too boring, so this may affect my experience as I basically never saw the stalkers. I don't regret that though. When I did encounter the stalkers it wasn't particularly interesting, as the strategy was basically just to wait for them to pass. That's especially boring in procedurally generated maps that have very long hallways. I guess it'd be more exciting if you were scared, but this game didn't make me feel fear. About the stalkers, I felt their designs were disappointing. First one was some crazy monster which was cool, second one was a magic femdom witch which was cool, and then the rest were just humans. They're supposed to be the big dangerous enemy but they're literally less freaky than the common monsters. Even the boss fights, the first one was interesting and challenging, the rest were straightforward spongy pushovers. There's a timer in the dungeons which feels really weird. From the intro/tutorial I thought this game would be about sneaking around, avoiding monsters. That seemed pretty exciting because it would play into the monster being strong and powerful, which would enhance whatever sex scenes they have. But then there's a timer that starts off paused; when it depletes, the invincible stalker starts hunting you down. If an enemy sees you, the timer starts ticking and doesn't stop until you reach the next floor (at which point this repeats). It's basically impossible to not get seen (the stealth mechanics may as well be nonexistent), so what ended up happening was that I just bumrushed through every level, beelining to the objective, sprinting past enemies and sometimes shotgunning them in the face. It was pretty trivial to do this and felt like a DOOM speedrun or something, not entirely bad but not engaging and not playing into the eroticism, there's zero point to doing H-scenes with this gameplay style aside from just for fun. Spoiler It honestly feels bugged. Like maybe it's supposed to stop ticking if you kill the monster that triggered it, so as to encourage stealth while killing enemies that see you ASAP, but just doesn't do that (sometimes it stopped after I killed a monster which is why I mention that). The game design feels disjointed and disorganized. No crosshair for some reason despite having guns, so get a crosshair overlay program ready. I guess I'm complaining a lot for a five star review. The game 100% has its problems and many easy areas for improvement and polish, in some ways it feels unfinished, as if the dev had a hard deadline to launch and had to do aggressive cutting to reach it (including cutting playtesting and design iteration/reworking/editing). But I enjoyed it a ton, it felt novel, and my overall attitude towards it is very positive. I'm only thinking about it and criticizing it because I liked it so much (otherwise I'd silently move on). I've played hundreds of games and most games can't keep my attention, so with that in mind this one is def worth peeping, especially if you're into horror games and/or freaky things. Better game than Death Stranding 2 that's for sure ;_; One last thing, actually the biggest problem for me: the final boss WILL do quite a few things to arouse you, Spoiler: Ending Spoiler and there is NO option to actually become her loyal pet. This leaves Demon-serving me rather unsatisfied.

Dev knows how to make a game, soul-like FPS with stats, perks, weapons, variety of enemies and annoying bosses. A gem if you're into horror and the soul-like challenge. Even has a good story arc. Fem Biltemakorv av Fem.

Probably the best horror game I've played so far. The levels can feel long and repetitive at first, but once you realize you don't have to explore every floor completely and that the door to the next floor is always visible on the map, it becomes much easier. The combat animations are decent, but an option to modify the NPCs' appearance a bit, to lessen the scary factor, would be welcome. (Google traductor not AI)

There's a lot of grinding, the story is there and generally understandable, but it still feels very empty. The gameplay involves "hiding" from the floor boss by placing lockers, but it's completely pointless when the timer adds time to simply entering and exiting the previous floor. The "entities" and scenes for them are repetitive, not to mention the clothing; they could have come up with better ideas for the new floors. Overall, I'm disappointed with the game; I expected more...
BobbySwegg 2026-03-12
I liked it. I played it until the end. It gets a bit repetitive, and the bosses have bit too much HP, but it was really good. I like the animations, graphics, sound, difficulty, atmosphere. I dont know, theres something special about this game.
iluvpink 2026-03-10
I actually think the concept is interesting, but the low quality graphics and the clunky combat system made this a DNF for me. My first try was on normal and I died repeatedly right of the bat, so I tried the easy mode and proceeded to die repeatedly but lasted a little longer. I never got to the point where I knew where I was going and never felt like I was catching on to the combat. I think the skeleton of a good game is there so maybe their next game will be more playable for me.

Mixed bag. +has a coherent gameplay system +small filesize +a few of the fem designs are solid (bosses, maid, stone girl) +good atmosphere (but to much creep imo) +voiced and intriguing +dungeons feel different Silent Hill inspiration very apparent towards the end -arbitrary room reset mechanic -cheap traps -not that erotic even repulsive at times -stretched in scope (play on easy and past boss 2 rush through there) -forces resets with enemy placements (in early game) -animations are mid for normal enemies and upper mid for bosses >you will see them a lot i see potential with the concept but this needed more attention and content. reduce the amount of orbs you need to open the boss room.
Mrsharap55 2026-03-06
Recommended to play, the graphics are good, animations and sound design is also nice, really loved the atmosphere and was actually a bit scared in the first hour of playing when i didn't knew much The weapons are fine, used the shotgun most of the time, bottles are really good if you have a lot of them, basically a gun without reload Completed the game in 6 hours 57 minutes

I normally give 5 stars to games that achieve what it was they aimed to do. Whether it's a simple game like a super linear VN, a side scroller or a brainless beat em up, so long as the author's intended goal was achieved, I give it 5 stars. Don't get me wrong, this game was good. The horror aspect was solid, especially early on. The rewarding feeling of playing it smart felt good too. The scenes were fine, although I felt more could be on the human ones (but it IS a horror game, so I get it). But man, not being able to have the ending that we all seem to want makes me a little bummed out. To get all the way to the 'big bad' just to be like 'oh...' Is a drag. I know there were some complications in the production and being burnt out is a thing. I sincerely hope perhaps we'll get some DLC down the road. All in all, this game hit all the marks save for that. Good story, good VA, good progression, a little grindy but gameplay was honestly fun as hell so didn't feel like a grind. I look forward to the creator's next work!

An amazing game with an amazing style. Combat mechanics are fun, the story is neat (if not a little predictable if you know the type), and the sexy stuff is pretty good. The game may not be perfect (one glitch made a certain level inaccessible sometimes due to overlapping geometry from the random map generation), but I can see this dev making some real masterpieces like this again. If there's a blueprint for future cool adult games, this may just be it.

General: Sin Spire is a well-crafted and (almost) complete 3D dungeon crawler with significant horror elements and a short story. Kinks: The protagonist is male and is basically purifying female supernatural entities of different kinds. Therefore, main kinks include horror and "monster" girls – even though they remain rather vanilla. Sex is almost exclusively oral and vaginal. The protagonist's dick is rather large – a plus for me! On the contrary the variety of sex positions falls a bit short, they often are quite similar. Graphics: The environment is rather well fleshed-out and the atmosphere if that of a horror game, though all in all not very spooky. The girl models have some variety and look pretty good for the game's style. Note that you won't see any 4K ultra smooth Daz renders. The animations feel smooth and natural. Gameplay: The gameplay has attributes to keep up (health and sanity) and a few melee weapons and guns to keep the girls at bay – or convince them to become "purified". There are 5 stages with some shared and some different monsters and 1 boss per stage. To advance stages, one has to pass all 10 levels of each stage, multiple times. Therefore, it can feel a bit redundant after some time but all in all you can pass it quite fast. At times you almost feel like a speedrunner. There are 3 different difficulty levels that seem to match different audiences. Other: I have to mention again that the game is complete (only one ending is missing and is said to be added soon(?)). Play time depends heavily on difficulty, the time one takes and experience. Generally I'd say you have roughly around 10 hours of playtime. Conclusion: For me the game is great, it has a unique playstyle, very little bugs, nice animations and is all in all surprisingly fleshed out for a game on here while also being quite niche.

I played through the entire game and while I find it entertaining it is very clearly unfinished. The gallery is bugged, only the enemies from the first level feature unique animations per monster, a lot of clipping, re-used enemies and animations past level 1 and many more issues. The last two bosses from the dungeons meaning the one with the twin tails and the nurse both are clearly unfinished. Neither of them being fun to fight because they have exactly one attack pattern. The one with the twintails just shoots at you with her pistol and throws a molotov at you. While the nurse just hits you with her melee attack which is easily parried. If you enter the gallery and look at the bosses you will notice two spots that are empty. Now this being Sin Spire and all the bosses being based on the 7 sins. I suspect there were originally 2 more dungeons planned and scrapped during development. Speaking of development Sin Spire is in a kind of weird spot in my opinion. It starts of as a primarily stealth game with survival horror mechanics similar to resident evil but once you reach the tower it basically just becomes a run and gun doom clone. Its like the dev clearly didn't know which direction to take for the game, first wanting a primarily horror focused game but then he went with automatically generated dungeons that got rid of all the creepiness the game had in the beginning. The story is also not very good in my opinion and made me roll my eyes. Spoiler The merchant girl is actually the big, bad succubus who lures in horny fools for their life energy wooooohh spoopy. But I think for all the negative criticism it is a fun doom-like shooter with all kinds of demons to purify. Personally I hope that the dev at the very least adds dlcs with more unique animations, fixes the clipping issues and improves the last two dungeon bosses. There is certainly room for it.

Im getting annoyed af. Hitboxes from Enemies are horrendous, way too many spawn too, next floor is just filled with traps where i cant get past without getting skewered 5x. The stalker is annoying on top of all that. Who thought its such a fun idea? Edit: HItboxes still horrendous, but once u get the hang of things and especially find a weapon to block etc., its just speedrunning the dungeons to the last floor, get a crystal and repeat til u unlock the boss
watermelonseed001 2026-02-10
its not a bad game. the gameplay isnt bad but i cant say a lot since its not my cup of tea. i cant get horny and scared at the same time. the atmosphere of the game is so scary bruh i had to delete the game after making it to the tower

Game itself is a 7-8/10, and thats considering that I'm not the biggest fan of 2D models (hurray for models clipping through each other! even if only one scene here has that issue.) Different poses, quite a few enemies, i think 8 and 5 bosses. Only issue is that the games ratio of new enemies to new levels is out of wack, leaving me a bit disappointed with the game's new levels as there is typically 1 or 2 new enemies per dungeon and you have to beat them as many times as you've unlocked a levelish (beat level 1 once or twice iirc, 2 twice, 3 three times and 4 4 times.) Enemies are nice, although a couple for me were definitely "OH DEAR GOD KILL IT" not "oh lemme tap that" (like the split head enemy. all the heebie jeebies). The biggest problem for me is that the final boss WILL do quite a few things to piss you off, Spoiler: Ending and there is NO option to actually kill her. This leaves Demon-murdering me rather unsatisfied.

Played version 1.0. The complete version it seems. This is an actual game with erotic elements to it. It has a rough start, may lag a little on some places for reasons unknown, but it can be fixed easily enough so no big deal. The H Stuff: If you're not into freaky, creepy-looking females or simply find it... weird, then this most likely won't do anything for you. Animations are nice and smooth, especially the bosses (which are not monsters). Nothing too crazy, but definitely looks good. Also there are two normal women in the game and yes you can have sex with them. Gameplay: Simple. Make it to the end of the dungeons, don't die, gather stuff up, fight the boss, move on to the next dungeon. There's a bit of a strategy at first when using weapons and such, and it may feel too difficult, but believe me, it gets easier if you are patient enough to gather resources early on. It's responsive and I never felt like the game screwed me over randomly. Also some sidequests for a bit of extra content, worth it if you really want to fuck those two ladies. You also get "free mode" which is a gallery really, once you complete the game. Graphics: The models for the women are actually very expressive at times. Game looks fine, nothing insane, but still pleasant considering it was made by one person. Savina's lopsided smile made me feel things... TIPS! - The butcher lady has a high chance of bugging the game when you purify her, making enemies and traps unresponsive in the current dungeon, allowing you to explore, use this! - Always back out to the previous floor once you go up one, works once and you will get some extra time for some reason. - Cheese it. Go in, fight enemy, purify, back out the floor if close to exit. This will stop the timer and make enemies return to their positions, giving you more room. - Floor 4 of second dungeon may spawn a golden "statue" enemy. Purify her and you get 25k gold! - Parry and hit them in the head, does tons of damage. Also, stealth attacks are a thing and most enemies will fall to one axe swing like that, two if they are strong enough. Butcher lady is the strongest though, just shoot her in the face. - You DO NOT need most of the skills available, only about 5 or 6, so feel free to sell any blessed shard you get while looting if you want, but unlock purification first. Shards give 50k gold. You need to level up individual stats to unlock skills anyway and bosses give you a shard. Also, focus mostly on Vitality and Lust, Mind doesn't matter much, the rest is up to you. - Look at Savina's legs! They will heal your soul. Entertaining enough, but repetitive and lore got interesting but I wish there had been more of it, and could have gone crazier with the enemies and animations. Still fun. Cool concept. Worth checking out.

I was a bit worried at the start. The first dungeon was really hard then I kinda figured out it was a rougelike and then it became easier. I sunk a fair few hours into the game. I 100% the game on steam and enjoyed even after.
qljrnt6jc4eh2 2026-02-06
Game version: 1.0 The thing that makes this game better than most of the rest in the same genre is the amount of details/ lore that has been put into it. It's not just a "Woke up in a horror maze, now get out there and finish the game", but a full story with features like lore-explaining letters lying around, NPCs with their own quests and a central "hub" where you will always go back after clearing a dungeon. The visuals are good, but in no way great. This can't be said about the animations , though: They are fluid af, the UI even lets you change angles, tempo and - sometimes- positions. The worst and most annoying part about this game is the immense grind: You have to clear the same dungeon up to four (!) times in a row until you will be able to finish it. Yes, the dungeons will be randomly generated (just like in the "Diablo" games), but this changes nothing about entertainment. I ended up doing short gaming sessions and then turn to other stuff/ games until I came back. You simply cannot "binge"-play this game. So, it's 3 stars for the concept and 1 additional star for the additional effort that has been put into the enhancements.

Really well-done game; the voice acting makes the game hotter. It's not free from bugs, but the game is fun. The only real issue with the game is that it can be repetitive sometimes when you have to pass the same tower more than 2 times.
