Plays great! you really nailed it.
If you can make it so music doesn't reset when switching levels and that blood trails remain; you got a pretty good rendition of Meat Boy.
Yes, great suggestions I am working on it.
I already know how to keep blood trails when you die (currently I redraw everything because of destructible tiles modifying my tilemap)
For the music I have a little problem, and have to get in touch with the composer (I think he has to enable loops in his tracker)
