An excellent computer game made in the '80s for the Macintosh. Perhaps this was not intentional, but the copy I played (with my best friend when we were supposed to be "fixing" the computers) had no manual, instructions, or "Help" command. As a result, figuring out what to do was half of the challenge of the game. The game consisted of a series of puzzles, each different from the others, with a consistent Tarot card theme. Obviously, since there were no instructions (beyond an occasional poem or non sequitur), solving one puzzle was no assistance in solving any of the others. We never solved it. I would probably give a limb for a copy of it today.
