Bacteria: Life & Death is a chill, meditative growth game about a colony of microbes learning to survive. Feed them, warm them, and watch them multiply — or accidentally starve them, freeze them, or drown them in toxins. Every stage introduces a new twist: viruses, mutations, temperature swings, chemical spills. There is no rush and no timer. Just observe, adjust the environment, and discover what tips the balance.

Move the mouse or finger over the petri dish to move the food source. Click / tap on power-ups to activate them. Use the buttons at the bottom to toggle heat, cold, and toxin controls. Watch the population meter and adjust conditions to keep the colony alive.
