The game of lives

Have you heard of The Game of Life ? It is a sort of simulation from the 70's, invented by John Conway, made of square cells, and that is "played" single. In this simulation, cells interact every turn and make the grid evolve in a complex pattern, until either the pattern is infinite or no cell remains. All this is governed by four simple rules.

In this multiplayer version, make  your species be the last one standing.

Purified game-play,  retro-designed, a simple but efficient game.
