Simple and fun, I enjoyed burning 6000 calories B), the game used the theme spin to win well, needing to hit skill checks or you loose speed was clever personally I suck at skill checks but I found the ones here to be easy enough to hit.
I'm not sure if there was supposed to be audio but I had none coming through, some sound effects like bikes running and some rewarding sound for when you successfully hit a skill check right and a negative sound for when you fail one would help lift this game further.
