Think things through

You're rather undecided, so you decide to browse the app a bit and think things through. You COULD immediately make everyone in the class super hot. It's an option. But who knows how this thing works? I don't want to mess up some body else's life without them even knowing it. So, in the end, you decide to experiment on yourself.

You turn the camera to reverse and take a picture. You then open the sidebar to see what kind of changes could be made. You see a lot of options. Too many in fact. And then, at the end of the list is one simple button that catches your eye.

[Random Changes 1-?: A number of changes are made at random. These changes could activate any feature or change any statistic. Note: If a statistic is changed that you previously didn't have, such as dick size for a woman, it only counts as one change while still taking place. For those interested in a little chaos, or unsure of what to do. Not recommended to use without extensive knowledge of app.]

You see this option and are immediately interested. Now, the better question. Who do I use this on? And how many changes?
