Nice game concept.
Unfortunately I tried to play this game 3 separate times and each time found the game was not playable. It seems the character wouldn't jump most of the times and when I did jump I didn't know where the end of the level was (if I reached it, the game didn't react to it) and found myself looking at a screen with no player on it.
The movement that I experienced when it did work was nice and the effects were nicely done.
Hopefully it is only me that has this experience. :)
