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.

How progression works

The entire environment is a single organism that depends on the Biomass Core being fed.

When the Biomass Core is hungry — passages are blocked

When you feed it — the organism retracts and reveals new paths

Doors are replaced by tendrils. Keys are replaced by food for the Biomass Core.

The core gameplay loop

find → grab → return → feed the Core

objects hidden in darkness that must be carefully spotted

small creatures crawling along the floor

organisms that hide or escape when approached

In the game, you are given clear objectives such as:

Active outgrowth: Mushrooms → Feed the Core (Mushrooms 0/6)

FEED THE BIOMASS CORE — RETRACT OUTGROWTHS (0/5)

Every trip deeper into the tunnels becomes a decision: how far can you go before you must return to the Biomass Core?

One location. Constantly changing paths.

item placement changes each playthrough

you never fully know what you will encounter when you return to the Core

Visual style: how you remember it, not how it looked

low internal resolution scaled sharply

limited color depth and dithering

classic 50/50 transparency effects

subtle geometry artifacts that make the world feel unstable

This is not meant to be pretty. It is meant to feel unsettling and unsafe.

What to expect

a short, intense horror experience (30–60 minutes)

a unique mechanic centered around feeding the Biomass Core

exploration of dark, organic tunnels

minimalist rules and clear in-game objectives…
