I was referring more to how being spherical prevents you from using most of your moveset and what counts as "tricks", keeping you from doing as well as you could during the rated trick sections.
Getting money and doing tricks during the other shapes seems fine, though.
Unrelated side note, suggestions:
1. A little glowing/dim OPEN sign for shops that are currently open/closed.
2. Some kind of change to how the text above the little trick block things appears; they're hard to read unless you get the camera really close.
3. Maybe a taunt/trick button that can be hit mid-trick to earn a little bonus points?
