Bubble Bounce

Use your bat to bounce bubbles around the screen and try to pop the swirling bubble targets.

Powerups on later levels affect the bat size, ball speed and other special effects.

Also has pretty swirly pattern generator code (accessed via menu button)- vaguely reminiscent of amiga demos, nice and trippy, lots of ways to change the patterns. (A more advanced version is available in the android marketplace under the name "Trippy Wallpaper").
