Simple. Arrow keys or WASD to move. Try your best mate. All levels (will eventually) be verified by me.
I decided, one day, "I am going to make a super cool precision platformer (partly inspired by the meat boy series, but not really) without any Scratching skills (i'll use my premade movement system from @griffpatch ), on Scratch. What could go wrong?" This project will be open while in development, so feel free to give me ideas? However, it may just be scratch cat for a little bit because I don't have too much free time. (or motivation. Or reason.)
