About Bacteria: Life & Death

You control the fate of a microscopic colony in Bacteria: Life & Death, a relaxed growth simulation where patience matters more than speed. Move a nutrient source around the petri dish to feed your organisms, then watch the population rise or crash based on temperature, toxins and other environmental factors. Each new stage adds challenges like viral infections, genetic mutations and chemical hazards that force you to rethink your approach. There are no timers or fail states, only cause and effect. Poki Games hosts this calm puzzle of balance where small adjustments ripple through an entire ecosystem. The appeal lies in tinkering with sliders and switches until you find the sweet spot that keeps life thriving despite constant new threats.
