The sound was excellent, loved the heart getting faster. My only critique is it was hard to figure out the match of the "Dice == Level" -- that could probably be spiffed up in the future to really centralize on it.
I also made the mistake thinking the movement was freeform and not on a grid. I think grid movement was great once I got the hang of it and really meshed well with the moving zone, just confused me at first.
Excellent entry!
