Hi, I honestly preferred the former music (hard to explain, but it fit the weird atmosphere of the game better? Also it was less repetitive.) That said, it's hard to leave this game after we start playing :p
The only way I see to improve this game is after we fall, have a camera that better shows all our opponents behind us stumbling on our body (losing is more satisfying than winning in this game sometimes :p ) I would also totally see a Crash mode, ala Burnout ^^'
