Somewhere far from your spawn point, something is wrong. Your compass knows where. Whether you go and see is up to you.
What is Clearness?
Clearness is a world-corruption survival experience. Once it is unleashed, an unstoppable infection spreads through your world, permanently turning every natural block to glass.
There is no cure. There is only time, and how you choose to spend it.
Features
- Spreading corruption — a glass front advances relentlessly, wave after wave, and grows faster with every in-game day.
- It hunts you — new outbreaks erupt near you every few seconds, wherever you go, in every dimension.
- Interaction has a price — interactions attracts the corruption. So does sleeping through the night. Choose carefully.
- Generated structures are safe — generated structures (villages, temples, strongholds, ancient cities…) and player-built blocks resist the transformation.
- Beginning of a journey — a seeker's compass points to the anomaly. What you find there, and what you do about it, is yours to discover.
