Chasing Stars is a Unity3d game that explores artificial life techniques and algorithms. The game's robots respond to their immediate environmental conditions based on an evolutionary genetic algorithm. Each robot's genes are different, and better-performing individuals are more likely to pass their traits to the next generation.

The game's levels are generated using a Lindenmayer system. The stars are animated according to a cellular automaton whose rules change based on the life and death of each robot. The environment reacts to the robot's progress by generating more challenging level designs and obstacles each time.
