New Version! Germ Battle
Several levels to choose from. Can choose how many of 6 defenders to use, and they each have costs.
The object of the game is to get a positive health score.
Set up a challenge for yourself (can you beat level 2 using only apples? How about with a spawn time of 5 seconds?)
I find it very Zen-like to set up your defenders and then watch the game unfold.
