ABOUT THIS COMPANION
A place for your discoveries.
MONOMOON Field Notes is an independent fan guide and exploration notebook for Gentle Giant's game. It is not the official game website and is not affiliated with or endorsed by the developer.
What this site covers
Our guides explain number symbols, map coordinates, the Red Temple entrance and its nine puzzles, published system requirements, and the developer's input recommendation. The notebook is an optional tool for your own observations. We do not host the original game or claim to provide a complete walkthrough.
How we write
Game facts are checked against developer materials and the official store listing. Number, map, and puzzle instructions are checked against named Steam Community authors, with dates and source records kept in our editorial notes. Original diagrams illustrate the documented rules; they are not game screenshots. We do not present it as an official mechanic or describe this research as a playtest. Initial facts were checked on November 14, 2026; game updates may change details.
Artwork and video
MONOMOON promotional art comes from Gentle Giant's Press Kit for editorial coverage of the game. All rights remain with the respective owners. The official gameplay trailer is displayed through YouTube's player; the video is not reuploaded.
