Got bored trying to draw trees for my rally game and did what I always end up doing, starting a new game.

Pretty simple, place blocks to bounce the ball into the glass. Level editor keys are PageUp/PageDown to switch levels, arrow keys to change the number of player blocks.
Levels are saved to .bouncyball/levels.xml in your home directory. I quickly knocked together 5 levels (pretty untested so probably better solutions than mine).
