The simple graphics and the relaxed music suited very well with the game. The music is catchy while playing!
The idea of the inputs not changing independent with the camera is nice. Whoever, I felt a lot dizzy after playing the levels with the camera rotating, being very unconfortable. I think this is a big problem for the game. If you remove the camera rotating effect, and think in other way to keep that mechanic of paying attention to the inputs, it can turn out in a nice game (perhaps some levels being upsidedown, others mirrored, and the ball having a indicator of its front? Exploring the motor coordination of the player).
Congratulations for participating! I think that if you remove that camera effect, it can turn out in a better game.
