Description

MODIFICATION APP is a transformation-driven experience that puts unsettling power in your hands. One day, a mysterious new app appears on your phone. Its shadowy creator claims it can alter your roommate in almost any way you imagine and, strangely enough, she seems open to it. How will you use this newfound control? How far are you willing to push the limits? There's only one way to find out: open the app and start experimenting.

Really enjoyed it. Maybe make it clearer that the branching paths happen at different times of day? Once I did a minigame twice, I started to get better at them, but they were mildly annoying trying to puzzle out. I also really want at least one branch to breed her, or officially romance her.

The game is Peak
Hands down a solid game

I'm actually very interested for more content to come to this game
Also, I will be so frank when I saw her with dog ears and tail (Pet Route), I genuinely wanted to pet that girl. Not even in the lewd case, I genuinely wanted to just pet her, say aww, and "Who's a good girl" type shit. My heart literally soften like a sponge at the sight.
