Carlman

Level1/6
Score0
adding mass removing mass target direction

Maze-chase game played inside Lenia, a continuous cellular automaton. Carlman is steered by CARL (Cvjetko et al. 2026), a reinforcement learning agent that keeps him on course by adding or removing a little mass at a time. The Carlman, the ghosts and the dots are all solitons: self-organizing patterns that move and hold together by the automaton's own rules. Eat every dot to clear the level and move on to more ghosts, grab a power pellet to make the ghosts edible for a while, and keep away from them otherwise: a ghost's touch dissolves Carlman. Use the arrow keys, or click or tap the maze, to choose which way Carlman goes.

Performance. The game runs entirely on your device. Models with a smaller Lenia kernel radius r or fewer parameters may run faster. If the game stutters, try one of those, or lower the game speed under Settings.

★ is the most stable. The other two may be unstable, and may need a different action cost or model.
