Stored observation / content update: 2026-10-25T09:34:50.000Z

A cozy nonogram (picross) adventure. Descend a living dungeon and fill a naturalist's journal one picture-logic puzzle at a time. 100 hand-crafted specimens across 10 floors. No fail states, no guessing: every puzzle is solvable by pure logic. Just you, a lantern, and quiet discovery.
