Use arrow keys to control Gobo Press z to swap to the place of transparent Gobo. You cannot swap if transparent Gobo is crossed out. you /can/ jump after you swap, but I like it so I will keep it in. I will call it swap jumping
All I need to do now is find a vertical scrolling mechanic somewhere. For some reason it crashes if you swap jump too much.(Fixed. Problem with any use of the space bar.)
