I've just blown half an hour on this game, which mightn't seem like a lot but I could've sworn I have only been playing for five minutes. The comical warning of being highly addicting seems appropriate. I've enjoyed the quirky cast of characters that I have come across thus far, the vibrant retro artwork is a treat too.
I am unsure about the movements of the characters, however. Is it intended that they have a margin of error, in which instance they either fumble the ball, or topple over completely? I can only assume it is as you would otherwise be left playing what would be a 20 minute marathon for one match. If not, perhaps this could use some attention.
The only other thing I could suggest that comes to mind, is adding a few more tracks in game. While there's nothing wrong with the track that plays at the moment, I don't want to be hearing this stuck in my head later on in my day. Overall: fun but slightly frustrating game play. (When blunders happen and you need your crucial match point.) 4/5.
