An interesting core mechanic that worked well and suited the theme. I thought the level design was on the whole good and the difficulty curve was pretty spot on. The graphics and sound were a bit basic though, and the controls were a little fiddly. It took me ages to realise that you could change your direction in midair so that you bounced a different way when you hit green blocks. Perhaps a mechanic to slow down time, or time slowing down when you're about to hit other blocks, would alleviate this problem.
