Space to turn into your shadow. WASD or arrow keys to move.
Everything by me, including the platformer script (finally!). Okay, this is kinda simple. You can only switch when it is possible to without getting stuck in ground. (To those old scratchers, about 4-5 years ago I remember something with something like this concept being featured... I couldn't remember the name of the project though.) I'm too lazy to make a changelog for this. That is, if I were a terrible person! 5/20 - Created platformer script. 6/3 - Added switch code 6/7 - Added switch conditions; you can't break the code now. 6/29 - Added a few levels. Played with the code.
