Animal Evolution Simulator

You start as a worm and grow by eating plants and mushrooms. As you grow, you move up through stages of evolution, all the way to the highest one. Each new stage opens the door to the next biome.

Plants and mushrooms are your food. Eating them is how you grow and push toward the next stage of evolution. Predators are a different matter: you attack them rather than snack on them, so keep your fighting skills sharp.

Move with WASD and jump with Space. The left mouse button attacks, the right mouse button moves the camera, and the mouse wheel zooms the camera in and out. Smartphone controls use a left joystick and a jump button.

Yes. You can explore the map and discover new biomes. Each time you step over the threshold to the next stage of evolution, you find out what waits for you in the next biome.
