Not bad
I liked it. It had the quickness and stuff of a good platformer.. but with some things wrong. It needs some kind of background, even if it's just a different colour. Check out my Crisis in HFRC, i couldn't be bothered to do detailed backgrounds either, but i just whacked in a red tinted gradient on the red level, a blue one on the blue level, and it livens it up abit, and it's easy to do. Also the character hovers above the ground a bit, but again, easy to solve. Improve it, get afew more obstacles and stuff and it'd be great. Also, this is the longest review i've ever written.
