Conway's Game of Life meets SimEarth

Create a Thriving World!

Place items from the stack in the map to create your world. In challenge mode, you loose in case the stack is full so pay attention to the stack size.
All items have an influence on the neighboring tiles, which may cause them to change.

As time advances, new tile types and life forms become available. If living beings are placed in congenial places, they'll procreate and spread.

In later stages, human beings can create cities. Humans placed on different tile types will have different traits and "feed" differently. When cities appear, these different traits will manifest as different civilizations.
