i like the concept, the graphics and the music!
I just found annoying that the camera doesnt follow the mouse when you reach screen edges, so there's nothing you can do to prevent the ball to fall at that point.
Also, i think the ball can actually drop from the front and back side of the platform (not just from left\right) if you move the mouse too quickly.
With some power up\obstacles this could be a pretty cool game to play. Good job!
