Description from the developer

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.
