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.

I am good at the mini games, but some of them, like the bimbo path level 4 I think? Level 3? Well that one is way too hard. I think your supposed to have a touchscreen for this.
