CHWÆST — Feed the Biomass Core to progress
A late-90s inspired retro 3D horror where progress is biological.
You don’t unlock doors. No keys — you feed the Biomass Core.
CHWÆST takes place inside a living organism. Passages overgrow, corridors tighten, and the environment reacts to your presence.
At the center lies the Biomass Core (the Core) — the only way forward.
Your goal: complete simple objectives, bring offerings back to the Core, and push deeper until you find a way out.
The entire environment is a single organism that depends on the Biomass Core being fed.
When the Biomass Core is hungry — passages are blocked
