Very good hope to see future updates with more paths and maybe more interactions outside of just the effects of the app. Your art is great love the style, good balance of simplicity and detail. cant wait to see more locations and characters

Rev @ Modification App [v0.8.0] Art's fine, no complaints. Writing is thin, but in a not-in-the-way sort of style rather than an incomprehensible-mess style. No complaints. Well, I say that but I like the implication that the roomie is into it and I think it would be hot to play more into that angle somehow. Porn was fine; only compliant here is the porn-to-minigame (fap vs faff?) balance feels skewed away from lewd, which as a degenerate I object to. TLDR: Harmless lil bit o' fun.

+ Cool art style + FULLY VOICE ACTED (HELLO???) + Branching Paths + Minigames that are actually FUN TO PLAY and don't feel like a waste of time??? This is a winner Yall better give this some love I don't want it to get abandoned ever (Also hope they make her buff)

The sheer potential of this game is insane, it's quite simple as of yet (0.7.0) but i can see SO MUCH being done in the future, akin maybe to the coffee machine game popular on F95, the animations are well done, games are fun, i'd love maybe a gallery and a few more scenes with "no path" so to speak but overall can't recommend enough and can't wait to see this project go further!

Protagonist was LIVING WITH a woman who liked him and needed a magic app to make a move on her. What a lad The basic idea is outstanding, visuals are good, Sex scenes so so I had different, maybe too high expectations for this game. I thought the modifications would somehow stack, and you had to wear down the girl or like, seduce her! But the actual game is all about following "paths" gatekept by minigames. The minigames are fun! And the paths are an ok way of fleshing this concept out but I'm underwhelmed by the final product. More scenes and better graphics aren't going to fix it, it's more of the general implementation that feels lazy Still, it's a good game for what it is: killing an hour while looking at tits. Points off for no gallery but bonus points cause the girl looks like my favorite ex

I LOVED this game and the concept behind it. The step-by-step transformations are brilliant, the art is gorgeous, the dialogue is entertaining, and I often found myself feeling awkward, surprised, or shocked—the immersion is incredible! There’s plenty of content in the different routes; I enjoyed every single one and they always leave you craving more. Gameplay is simple and direct, no filler. As suggestion, besides more variety in certain routes, it would be character customization (even though her look already changes depending on the route, sometimes drastically). 5/5, going straight to my favorites. I’ll even recommend it to my girlfriend, seriously fun stuff.

Love the concept and the additional systems not seen in most VNs. I love the idea of the tree-system for modifications. Hoping there will be other girls too. Looking forward to seeing where this project goes.

Ver: 0.7.0 As of this version is a very good game, only thing is that you have to go back and play every minigame when restarting the modifications. But the art is good and i hope this game gets the development it deserve.
Kingwhoisnot 2026-02-10
Amazing potential. Plenty of kinks and sex scenes, also nice to have a transformation game that isn't main character focused. Art is mediocre, but the good writing and fun mini-games make up for the fact. A lot of choices to that are easy to track in the app. Only thing that I am worried about with this game is that the creator will bite off more than he can make with these branching paths. And the constant self promo of his patreon worries me that he is going to make updates really slow just to milk out his revenue. But seeing how the devs didn't do that yet, I have hopes for this game

Excellent little game so far. Think wario ware for the DS but with sex outcome! It is honestly so simple. There is only one QOL feature missing and that is to be able to revert to specific points in the transformation. I understand then it would be super short but I am confident it would not impact retention too bad. Guys it even has voice acting!

Modification App really caught my attention, especially because of its animations. While they may seem basic at first glance, they are much more impressive once you’re actually playing. The art style is very original and, most importantly, it stays consistent no matter which modification you choose for your roommate, which is something I really appreciate. The routes are interesting and there are quite a lot of them for the current version. I’ve played games with much higher version numbers that offer far less content, so this is a big plus. The mini-games tied to each route also add variety and make the experience feel more engaging. For future versions, I’d love to see at least one new route added, if that’s the direction the development is going. It would also be great to see more animations, especially during important events. If animations aren’t the main focus, then adding more images throughout the routes (not only during transformations) would be a very good alternative. I understand that animations and mini-games take time to develop, so this is meant purely as constructive feedback. Overall, the game is very well put together and has a lot of potential. Focusing on this main character first and later adding more characters with similar route structures sounds like a great idea. The concept feels fresh and original—I hadn’t played a game like this before, and it’s exactly the kind of experience I had been looking for: a transformation-focused game with a story, solid gameplay, and good visuals. For now, this is a 10/10 for me. I’m even considering supporting the project on Patreon. With or without money, I genuinely support this game and hope to see it fully finished someday. I used ChatGPT for the translation; sorry if anything is misspelled.

Very nice short game, still only has a short amount of content but I can see where its going and cant wait, there is no way to replay lewd scenes other than resetting but so hopefully they add that down the line.
DMSTS 2026-02-09
[v0.7.0] 10/10 small game that feels finished. And obviously will get more content. Finally a "not finished" game that feels very good, finished and polished. Love it. -Renders Good 2D art. -Sound Basic sounds, heard them in a lot of RPGM games + some BG music. -Playability It'll take you 1-2 hours to finish and I recommend to finish 1 branch fully, then reset your progress and start another one (cause you'll get a little additional branch). Or you can go towards "boob expansion" path to unlock it (you'll get bonus branch after 9 "changes"). -Performance Works okay. -Bugs Didn't see any. -Animations Still images with some effects. Nice. -Voice Acting Cool voice actor for the girl. -Grammar Didn't see any. -Amount of content Awesome 5+1 branches visual novel with mini-games. Everything feels polished and prime quality. Wish to see finished project and hope dev will add 10 or more other branches and bonus branches that are as long as base ones. Love the game in current stage!

Very good potential. It's got tons of weird niches kinks. Although still quite early in development. Hopefully it becomes really good. Slight nitpick to reduce to 4 stars: I hate having to redo every minigame just to check a branch. Seems a bit redundant.
Awesome Quest 2026-02-09
10/10. no notes finished the mind control branch. loved it my only request is more content. more events, more branches which I know you're already doing! keep up the good work. maybe a bit more flow between events? more on how this affects her day to day
Perelesnik 2026-01-31
It was perfect. Down to the last, minute detail. Despite the small amount of content, the art are amazing. Game have incredible potential. The repetitive gameplay may be stressful, but not too much. Worth the time
place_slave 2026-01-11
its an amazing game i wish you could travel back to a previous state so you dont have to redo when trying a new path the voice is amazing and i love the game cant wait for more modifications becuse it was hot so far
Yournewowner 2026-01-02
Amazing game that is keen on exploring all the modification fetishes, looking forward to more great art, minigames that are actually decent, and of course the smut that's actually got a VA that has grown on me overtime. It is almost IMPOOSSIBLE to find such good bimbofication in this economy.
Balatro Balatrez VI 2025-12-31
Very simple game fun and enjoyable minigames for one handed gameplay, which I enforce other games could do as well, since I still haven't gone pro using feet on the keyboard. Great scenes and voice acting, with a simple story to cover it all. Splendid
yamamoto0413 2025-12-30
This game is fun. It's still early with not too much content, but the art it cute and the idea is executed pretty well. I'd definitely recommend this as is, but I can't wait to see it keep getting more content.
