About this game

The Moss Codex is a grid-based stealth crawl through ancient libraries overrun by living moss. Collect prismatic spectrum shards and burn the moss to clear a route to the exit stairs, but the firelight draws patrolling Guardians, so time each ignition and wait out their gaze. Each floor is procedurally generated and grows larger and more dangerous as you descend.
