-TODO:
-* Maybe player should change orbit direction (and/or speed) with the orbit he jumps into?
-* Make sure orbits don't have too many obstacles.
-* Maybe skip player and obstacle updating while scaling?
-* Current min and max speeds of obstacles should be closer to each other.
-* Maybe background should tint with an offset on the colorwheel?
-* Rotate orbits with obstacles statically distributed on them instead of calculating obstacle positions (for performance).
-* Would also be cool to be able to jump in AND out of orbits, but hard to implement. Or maybe just tap on the orbit to go to?
