Your game look nice but I don't know why I had a lot of trouble mapping the keys to the direction of the movement, and I ended up falling off the levels a bunch of times. I would also advise against restarting the song at every reload, even more so when you basically have to restart several times to finish levels (the solution is not always obvious.)
Apart from that, as I said it looks good, the music fits nicely, and the levels are smart. It's a pretty good game.
