Design organisms. Evolve brains. Survive the dish.
Bacterium is an artificial life simulation where you design microscopic organisms and watch them evolve, fight, eat, and reproduce in a petri dish. Each creature has a neural network brain that mutates across generations, learning to hunt, flee, and mate on its own.
Build your organism from components - spikes for attack, flagella for speed, receptors for awareness, membranes for defense. Choose your look, drop them into the dish, and see if your lineage can outlast the competition.
Features:
- Design custom organisms with pixel art editor
-Neural networks that evolve through natural selection
- Multiple levels with unique challenges
- 9 visual styles plus custom cell designs
- Track lifetime stats across all your experiments
- Watch ecosystems emerge from simple rules
