An entry for the GMTK Game Jam 2026 titled "Count Down".

While the clock counts down, you should also keep the colony count down.

An extinction puzzle with clear inspiration from Conway's Game of Life and Schelling's Segregation model. Your goal is to purge the plate while managing the evolution dynamics of the microbes. 

Controls

• Click on a cell — Place antibiotic
• Wait / Space — Let the plate evolve
• Undo / Z — Retract the previous move
• Restart / R — reset level
• Ghost overlay shows next outcome (can be toggled off)
