Sarah is a girl with super powers, trapped in an evil villain's secret complex. In Sarah's run, any surface could potentially be the floor at some point, but there is only one way to escape, you'll have to warp your mind to as well as gravity to figure out how to get there!
It started with this drawing (of a firl I originally called 'super Maria' >_>) from there I had to make a character model, and from there I had to put the model in a game :)
