Excellent and Fun game. Adding a bit of a power while holding the power button to throw the ball would add more oomph to the already great game play mechanics. Keep it up :)

I just had a look at your game.

It almost seems like a cross between a puzzle maze, snooker, and spinning tops of doom.

I liked the style and the music, and had to try getting all the spinning tops to the "portals".

It took a moment to figure out what to do, you might want to add a description to your project page that lets you know what to do, and maybe a little spin on it, like "you are the last worker robot in a factory needing to clean up the death devices after an accident", or something.
