Enter the world of tiny, virtual protozoa. Take control of one in free play to just explore or attempt to outlast another on a variety of custom boards. The controls are simple, but in the spirit of experimentation you'll have to figure them out on your own by playing. Don't worry, though: if your protozoa doesn't make it, you can always relax and keep watching to see what the other virtual protozoa get up to...

Once you've figured out how to control each proto-type (ha!), the Challenges mode lets you pick a type to try and outlast.

Each challenge board is customized for the specific face-off!

So, grab your mouse, keyboard, and/or controller and GO!
