20 level version now out! Play it at http://scratch.mit.edu/projects/1368358/. Move with the arrow keys. Step on all the squares to move on. Once you're done, press space to have your attempt checked. If you've stepped on every tile when you press space, it will move on to the next level. Should you complete level 10 it will start over, but it glitches and you can't do level 1 again, so press the green flag if you want to play again. Blue and pink squares are warps. Grey squares turn white after you run over them. Light grey turns grey when you run over them. Look out for moving enemies!
