The Board Game With No Rules

About City of Six Moons, from BoardGameGeek:

City of Six Moons is an alien civilization game in both senses: a solitaire game in which the player guides the destiny of an alien civilization, and a game from an alien civilization. Inside the box you will find the components needed to play the game, and a rulebook written entirely in symbols and icons. You will need to decipher the game's rules yourself. You will never know whether you've gotten it right or not. No mechanisms are listed on this page. The designer will never answer any rules questions.
