Mess around with Scratch the Cat!
Controls
Left key left, Right key makes you go to the right lol. P turns you into pixels. W makes you the black hole. C changes your color for a long time. S makes you big, B makes you small. Space clears everything (except stuff that repeats like color).

Scratch the Cat is Scratch's mascot, not mine. Scratch is a very good beginners tool for Video Game creating, I think you should try it out if you want to get gud.
