Build creatures. Watch them survive (or die). Start simple. Add predators later.
- Biots evolve, hunt, and die on their own.
- Use the builder to make species and throw them into the food web.
- Start with flowers, then add hunters once the world has food.
How to play + what you are seeing
Good first move: spawn a few flower types, let the world stabilize, then add hunters.
Builder: click segment chips or endpoints in the preview, change type, angle, and length, then spawn.
Inspector: click any biot in the world to inspect it and save survivors back into the builder.
Legend: green/photo feeds on light, red/predator bites, blue/propulsion moves, gold/reproduction lays eggs, gray/structure supports, silver/armor hardens.
