A spark in the brine

Everything begins here. A few strands, and room to grow.

A FIELD GUIDE TO FIRST LIFE

A little life, in about ten minutes.

  1. Hold Gather for RNA. Hold Synthesize to exchange 2 RNA for 1 DNA. Keyboard: G and D.
  2. Grow organelles to make RNA automatically. Two organelles unlock nuclei, which turn RNA into DNA.
  3. Balance production. If nuclei consume RNA too quickly, switch them off or grow more organelles.
  4. Make room. Membranes store more RNA; cell chambers store more DNA. Mitochondria multiply both expansions.
  5. Evolve three times. Save 150 DNA for reproduction, 175 for a lineage, and 200 for multicellular life.

All three lineages share the same economy. Each reveals its own ending and keeps a cabinet token. New tide resets this run and preserves those tokens.

Progress saves locally every few seconds. Pause with Space. Sound is optional. The game progresses only while this tab is visible.

Begin another tide?

This resets the current cell. Collected lineage tokens stay in your cabinet.

SOMETHING NEW IS ALIVE

A world begins.
