About MONOMOON

MONOMOON is a single-player, nonlinear exploration and puzzle game from Gentle Giant, available on Windows PC through Steam. It centers on environmental puzzles, unusual items, hidden paths, and discoveries made by observing and experimenting.

Progress follows clues rather than a fixed sequence, so returning to a place with new information can open a different way forward. The developer estimates about 10 hours for completion; exploring deeper secrets can take longer.
