This is some old thing I made which I recently decided to revive. It's really not a game with an objective, but it is interactive, so I thought I'd submit it.

Also, please don't tell me I fail biology forever. I know it's not accurate.

WARNING: This is a sandbox/simulator, not a game where anyone wins.

Basically, click anywhere on the screen to place bacterial cells. Bacterial come in all sorts of flavors with different behaviors. (Note: There are 4 species, colors are purely decorative.)

Also, the options and graph buttons let you view the options and the graph. They're kinda interesting.
