It stops being the world's largest tutorial after you exit Chapter 1, at which point the levels get sort of enjoyable. But the minigames, cutscences, etc. are all terrible.
I find the camera in the level 3 time trial is a bit slow, refusing to keep up to speed with me. Also, the 3-second cutscene at the start is a bit annoying...
I feel like the physics are kinda against the human players: Slippery mode doesn't effect the CPU players at all and that awkward thing where the ball slides out from under their feet and backwards into their own goal never happens to them.
The knocking on door part is HELL. You have to get the taps just right or else all the letters will be discarded, which is really hard when there's even a teensy bit of lag.
