You cheated! I'm sure you started this game before the jam started! Maybe you started coding on this, before aduros came even up with the idea of WASM-4. I refuse to believe, you managed to make a game as awesome as this in so little time!
In all seriousness though: Awesome game. I'm impressed by a lot of the submissions. But this is impressive not only for it's graphics, but especially for the audio. Very well done!
