Very challenging, but extremely fun if you can get in the groove

Great game, hard to master fun to play its all about competing with others that makes it fun. Wish you could watch peoples videos for best times.
Whats with the ranking system!?!? Its very wonky and unclear. Wish this could be more clearly explained or illustrated. I would have given this game 5 stars but no game is perfect. For what this one is however its pretty darn close.
Would some please explain the ranking system though. It doesnt make sense.
Otherwise fantastic job :)
