Movement: W - Jump A - Left S - Down (Only if you get stuck in a frictionless zone because you added an unknown colour) D - Right Colour behaviour: Blue sets velocity to 0, so you don't fall when touching blue. However don't make a completely blue platform as you'll get your head stuck in it. Black moves you up, so if you happen to have a velocity uneven with the height of the blue platform you move up to touch it. Yellow bounces you horizontally. You can't wall jump, but someone could make a remix for that!
Old description: Bouncy physics engine thing. This is an engine you can make your own platformers with. Remix ideas: - An adventure-platformer - A spaceman platformer with reduced friction and gravity - And just a plain old platformer.
