What the game is

Possess a vessel. Descend. Extract. Rebuild.

GRAIN ROT is a physics-heavy dungeon crawler where your Living Spark inhabits wooden vessels, explores shifting ruins, secures resources, and expands an Outpost between runs. A broken vessel is not always the end—but a full party wipe before extraction costs unsecured loot.

Evidence boundary: we have not published default key bindings, enemy tactics, or crash workarounds because the available official evidence is not yet enough to support a reliable step-by-step answer.
