In the Moonlit Tower, you explore a small 3-story tower to help remember who you are and your past. Like Dreamhold, the key to your memory seems to be masks, but much of the game, you don't know what to do with the mask.
The setting is dreamlike and very poetic. It is the game most likely to find its way into a book of poems or an art gallery. The author borrowed its imagery and story from several cultures, including Mongolia and China.
The puzzles are mostly the examine/pick-up-object type until you progress very far, and then they get a bit more difficult. There are multiple endings, some of which are hard to find.
