You are the yellow ring, a creature in the colony. Move with WASD/arrows (it moves one step per tick). Space or the Act button: strike an adjacent creature if there is one, otherwise eat. Survive as long as you can. Reproduce with R when energy > 30 — children join your family and copy every move you make; you lose when the whole family is gone.
