You are transported to Seleos, a moon of the planet Menra, where a note from Ektor Turren—a survivor of a cataclysm—promises you his accumulated treasure. Explore the islands to learn about Ektor and his world, locate the treasure, and find a way home.
Progress depends on exploring, observing, listening, and solving puzzles built into the islands’ machinery and surroundings. Notes provide story details and clues as you investigate devices, signals, and other mysteries.
Navigate the 3D environments with mouse-based point-and-click controls, using connections between islands to revisit places as you work through their puzzles. The game is designed for unhurried exploration, without a time limit or interruptions.
Players who enjoy Myst-style adventures often praise Haven Moon’s carefully rendered islands, quiet atmosphere, and environmental puzzles that fit into the world. Some also value its reflective pace and the sense of exploring a compact mystery. Reviews differ on the puzzles: some find them fair and intuitive, while others report vague clues, searching, and backtracking; many describe the adventure as short.
