I couldn't get past the first level, the top right corner just seemed to randomly box me in, and it was just trial and error of every possible movement in the hope something might work. I couldn't understand what was going on so after a lot of restarts gave up. I think with a tutorial that explains the mechanics this could work great, but at the moment I'm too lost. Really like the art style and sound though. (I had a similar problem with my own game - without an explicit tutorial it didn't make sense to a lot of people, argh)
