Ah memories... Good start, but I take it space is fire and not jump? At least that's what it seemed to do to me. In terms of improvements or things to do next, how about health bars, different types of attacks or smoother jumping? Nice idea though.

It'd be cool if I could smudge the wet paint around... Going back to the infamous quote - why is it that if someone tells you there's billions of stars in the universe you believe them, but if someone tells you there's wet paint you have to touch it to be sure? :P

Even with the speed slider this still seems either very fast or very jerky. Making everything move in much smaller steps will make the whole game appear far smoother.
