MODIFICATION APP
is a 18+ transformation-focused erotic visual novel game in development!

Synopsis

You are given access to a brand new MODIFICATION APP on your phone. A shady developer tells you that you can use it to modify your roommate any way you see fit - and even more she's into it? What will you be able to do? How far will you be able to go? Only way to know is to dive in and start MODIFYING!

About

The project has been in my mind for a long time, as a game I always wanted to exist. A game mostly focused on fun transformations and the fun events that come from those scenarios.

Some of the audio cues in Bimbo 4 are de-synced, they trigger on the next panel(?) after their respective texts rather than on them.

Absolutely great game, hope they add a android option and continue to update the game (excited for the futa option if you can't tell by my name)

(+3)(-3)

the growth path shod split in to futa or amazonen

(+5)(-2)

Will there be a Pregnancy Mod?

(-2)

i wish

Will there be a futa in the game?

I love the mix of NSFW content and just straight comedy that this game has.

(+3)

started playing for the BE path. Now growth is my new favorite! Best path by far. Hope we can see her get much bigger in future updates. Absolutely love your work!

(+1)

I’d love a save export feature, maybe one that just generates a code. I started the game on my phone for a quick test, but I’d like to move to PC when the next update drops. Since I’ve already completed all the paths, replaying everything would take too long.

(+3)

as the tree expands i hope more and more for just being able to click on the path guide and it turning mia into that path

(+6)

Can you please add a feature where you can load modifications you've discovered? 

Now that there's so many paths it would make things a lot easier. 

I feel like being able to load them in the paths app would be perfect!!! 

apologies if this is already a feature.

(also cough cough dominatrix...)

(+4)

Since I am kinda broke atm I am curious what won poll 9?

(+2)

Goth won, we’re eating good next month

In growth 3, she said "wait wait" while the captions say "wait wait wait"

(+2)

I do notice that my headphones register the majority of sounds in teh leflt ear

(+2)

So far I really do like it, though indeed a gallery would be nice. Also probably for future updates but more interactions to have when you're not growing them, or more variation would be quite nice.


Also agree with two other comments, that I love how its confirmed she is not just fully consenting but also able to opt out if she wasnt okay with it. As well as that an Extreme weight gain path would be great.

(+1)

isn't there a way to make an android version,tested it in the browser and the game is amazing

(+3)

Just a great game with great potential all around!

I like the dialogues, they feel believable, and Miera is doing one hell of a good job bringing Mia to life with her voice acting.

The minigames for the mods are varied, quick to understand, and easy enough to not get frustrated, but challenging enough that they don't feel pointless.

The different paths also offer a good variety. I especially liked Bimbo, Pet and Milk.

(Also, nice that it get's confirmed in the intro that Mia's actually fully consenting and into these whole shenanigans. I like it betterthis way)

Really looking forward for what comes next, and what wacky paths will get added in the future. (I think there was already talk about a Milf, muscle, and shortstack path?)

(+1)

finnaly after all these years i finnaly have it all

(+4)(-1)

wonder if belly inflation/expansion will be added (or simply put behind thought for this game considering it is about body modification or smth) 


anyways cool game

I can’t do the second bat flight mini game, it’s either I’m on iPhone or it’s just impossible, an I’m guessing it’s because I have a severe skill issue 

(1 edit)

Great game! Noticed a bug with milking where if the game doesn't end before the next bucket appears, you have a window to start milking before the minigame shuts down. If you do, the sound of milking never stops. I had to save and reload the browser to get rid of it.

(+1)

Thank you for reporting!!
While I couldn't replicate the issue, from looking at the code, I think I was able to make a fix to force the game to stop the sfx if it's still playing.
This will be added to the next update (next week).

(+5)

INCREDIBLY promising game. The minigames add some nice actual gameplay without breaking the flow, the art is great, there's voice acting which is super rare and quite appreciated. Really just great all around.

If I had to suggest some things (other than the obvious of more content), it would be a sex scene gallery so you can go back and see your favorites again without having to replay minigames and skip past dialogue. Also (at least in the web version) there doesn't seem to be a way to access the settings once you're actually in the game which is odd, but I'm sure that'll be fixed soon.

(+3)

Thank you for the nice words!!

The pause menu/settings are accessible by pressing the escape key, and I forgot this made mobile devices unable to open it.
This will be fixed on the next update, thank you for reporting!!

Gallery is also planned for a future update!

(+3)(-1)

Please do the weight gain women! Please

(+6)

Android version?

Not sure if its a mobile problem, but the game seems to slow down at around the third path, no matter which ones are picked. I like the art style and voices, though!

(+7)

reached the end of all current paths and DAMN! Tightly sir this game is WILD.

(1 edit) (+3)(-3)

I have only done the first transformation line and I am already incredibly flustered, heart beating (then again I am not the hardest to do that to). I wasn't expecting it to be so well done. Honestly the only thing I'm wishing for at this point it also be subjected to being transformed. I love being transformed just as much as transforming others. And for me it's practically always MTF. I really like this game and how you have done it, I look forward to more in the future.

(+10)(-1)

THIS GAME IS SO FUCKING PEAK. MORE CONTENT NOW!

(+1)

Name befitting the post lol

(+2)(-2)

I gotta find an audience for my game like how this game does, I'm screwed. rip snowv

(+2)(-47)

You're mentally ill.

(+16)

Your the one that pulled this game up

(+6)

do you need to talk to someone? Are you alright?

um I'm on bimbo level 2 and its telling me to play a game while waiting on her but I have no clue how to do that, can someone please help me Tv

(+1)

Go to the living room at afternoon, then you can "Play videogames"

Love this game. I'm finally checking out 0.6 and 0.7 after months, but I recently switched to Linux. Using Wine, the game runs very well, but there's some minor visual glitches. If possible, would you consider adding a Linux download for the game?

I have very different experiences with the game running under WINE.

The girl's model is entirely invisible, except for the eyes and mouth, and performance when she's supposed to be visible tanks. The console/terminal gets spammed with D3D messages  where something is not implemented.

Point is, a linux build would be nice and hopefully isn't too big of an issue.

How do i select a path? everytime i reset, it defaults to mind control

(+1)

you have to do it based on location and time of day, as well as which events you've already done in your current timeline

i crash at the sleeping part in the new milk section, i play on phone and no other parts of the game crash. just a heads up if you’re able to fix this it would be much appreciated

which sleeping part? the one in milk-2, after Mia gives you a bottle of milk, or later?
also what happens when it crashes? does some message popup, does it just freeze?
what browser do you use on your phone?

you’re right about the part, and what happens is the page auto-refreshes. it consistently does this and i use google chrome as my browser

i’ll try every other path and see if i run into any trouble, i haven’t tried any others since the update.

it happens very frequently, i’d say every 3-5 mins so im not able to finish paths. happens on any path i try

How do I select paths at the start? For some reason, I cannot change to the blue path at the beginning, and when I am doing the Growth path, it stops me at the 4th lvl because "an ongoing event is happening"

(+1)

try being in the kitchen at morning

(+1)

its definitly a different type of game in a good way that is cuz alteast to me nothing felt cluncky and the minigames werent just thrown in cuz idk honestly i personaly find them fun but oh well maybe that would wear of after playing this game alot not sure all i know is i like the game and it defenetliy feels alot better then the usual nsfw slop im used to

also i played abit more because i find it intessting beyond the nsfw part and holy moly theres so much to do and it all has voiceacting from how far ive come atleast this really is the oppisite of nsfw slop im used to 

(+7)

Some day we'll be allowed to walk in on Mia in the bathroom, someday

(+4)(-1)

Will Futa be in the game?

(1 edit) (+7)

Pretty peak gng, i hope u makin hella bag off this. (cant wait until the next update)

edit: Noticed there wasnt a gallery in the game, i would definitely suggest adding one so scenes can be replayed easily

(+1)

This!!! I have found myself loading save points like crazy when trying to rewatch scenes lol

web Android crashed when i go with milk route

(+1)

cannot replicate this issue on my phone.
when did it crash? after the milk minigame?
what browser are you using?

(+1)(-3)
