You start with three different cells, at first forming three single cell clusters. All cell clusters generate one cell in a set period of time, which are added to their clusters. You can change the color of the cells by combining them with different cells.

Soon various enemies will attack your cells. Some cells have protecting from certain enemies or can be used to minimize damage. You should try to balance the amount of cells, and make sure that all three cell categories stay alive in order to defend each other.

The goal is to lose as less cells to enemy attacks as possible.

In the sandbox we includes you can play with the colored cells to see how they interact with each other.
