A multi-platform entry, very impressive!
The game is quite cool too, simple to understand by fun to play. The levels difficulty is very well balanced. I tried the Megadrive version, and I think it would be better if you could map the "jump" to a button instead of "up", but it's still very enjoyable in its current state.
Graphics looks nice, and I'm amazed that you managed to compile it so many platform at once in such a short time-frame, congrats!
