37 and 39 are really pissing me off. the stupid floating paths are impossible to stay in control on, so you cant get all of the pickups without going through a second time, and the bowler brothers are just terrible.
after you play it for a while, you start to get into the swing of things, and the game becomes pretty enjoyable. story mode was good, even if it was a little long, and the challenges were pretty easy once you knew what to do.
