This is a simple evolution simulation. There are two types of organisms and two types of food. The Green organisms (type 1) eat grass. The Purple (type 2) organisms eat mushrooms. The grass grows all around, the mushrooms grow near the center. As the organisms grow hungry, they change color. If they run out of energy, they fade away. If they live long enough, and have full energy, they EVOLVE into two new creatures with slightly different attributes. Try it out. See how many generations (extinctions) occur per type, and how large the population can get.
