Use the arrow keys to move, Space bar is restart level' Light Blue is ice, it makes you move incredibly fast! Red is lava, it kills you... dont touch it Bright Green (not in-game yet) is goop, its sticky, so you cant jump in it. Blue, (also not in-game yet) Is really bouncy, try and touch it, and it will launch you. If you are touching a wall and you press up arrow, you will do a wall jump!
I say thanks to slenderm and uxan for making most of the stuff for me.
