WASD to move (in no relation to the planet; sorry, I probably won't be updating this) Press space to jump. Also, watch out for Satellite Pico! (He actually doesn't really do anything. But hey, who cares?!)
I used HD123's guide on how to make gravity. It's super simple and easy to use. Also I would like to thank the Scratch Team for their OHMYGODTHEY'RESOADORABLE! characters, such Gobo, Pico, and the Scratch Cat!
