The physics work well, and the puzzles are good. I have just a few gripes with the game:

1. Checkpoints aren't placed in spots where they absolutely should be placed. This leads to replaying easy areas that lead into trickier areas, sometimes over and over to the point of annoyance.

2. The camera has some wonkiness (which is actually poor level set up) and leads to situations where you can't see the ball. This is less of an issue than #1, but from time to time, it's still annoying.

3. You can easily screw up on loops by pressing in the wrong direction (which is actually the direction you start the loop on). In most games that change your direction while moving, the movement continues in the direction of momentum as long as you keep the movement button pressed in the same direction you started with, which is what they should have done here.

4. Level size is much larger than one would expect starting even from the first level. Smaller levels up front, longer levels as you progress should be how it goes.

Overall though, a decent game. I would prefer if this was more of an RPG, as the levels are long enough to support some kind of progression for the ball (more speed, better control, etc.).
