A simple little game that will drive you into a homicidal fury.
I'm not sure if that's a recommendation or what.
You push the solid white ball to the target -- the rotating circle with "Next" in its centre. Solid white lines block you and the dark blue spheres suck you into oblivion. You can play it either in "Push" mode, where the number of pushes is tracked or in "Time Attack" mode, where you compete against the clock. (To start either mode, click on the "Level 1" bar at the left of the screen.)
That's it? That's it.
Warning: Music and sound effects, though nothing too obnoxious.
