About CHWÆST: A Creeping Parasite Horror
CHWÆST — Feed the Biomass Core to progressA 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.
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?

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
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
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
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

It's... alright. Beat the whole game in 40min and there was almost no story to it. This feels like it's a demo or should be free to be honest. It's not bad, and I enjoy a short bite-sized game, but there's no meat to it. I'm surprised because even though it's a solo dev, they have made many other fleshed out games, but this one is disappointingly vapid.16 found this helpful
Chwaest is really disappointing the game is way too short and feels more like a demo than a full experience just when it starts getting interesting it suddenly ends also its not even that scary for a horror game it just doesnt create real tension or memorable moments.1 found this helpful
Fun little game. Only critique I got is the running worms were a little to hard/annoying to pick up. Fun time for the price though! Hope there will be more games in this universe!
I had fun with this. It's a short game, but I think the price is fair for the length of the game. My playtime says 35 minutes, and I was able to complete the whole game and unlock all of the achievements in that time. What really stood out to me though was how mechanically developed the game is for such a short title. Water sounds good and slows you down, the lantern you hold swings around as you move and has real momentum to it. There's an inventory system, stamina, jumping, light mechanics, crouching and crawling... It definitely feels like some of these were kind of put in as tests for the developer to flex their muscles; the lamp for example you can collect fuel for, turn on and off, refill, and it even dims the less fuel there is in it, but overall collecting fuel doesn't add a ton to the game, you never seem to be in real danger of running out and there is some ambient lighting that keeps you from being blind without the lantern on. But I also don't think it really detracted from the experience either. Atmosphere is nice and definitely had a creepy vibe to it even if it's not going to be the "scariest game ever." But an enjoyable experience, interesting concept for a game,…
Fun little indie horror game. Very simple and a little buggy, but nothing gamebreaking as far as I can tell.
Super short but its not bad. Easy achievement farm while being a decent entry into a spooky game. Great for the kids.
