Fingertips: I Walk Along Darkened Corridors

This is one of the one-move games from the Apollo 18 album.

You are dumped in a room with a huge number of complex counting and mathematical clues to give you the combination of a door. This is a beast of a game. I am a professional mathematician, but I ran fleeing from this game to the Club Floyd transcript, where I discovered this game was, in fact, incredibly hard.

The writing is top-notch Andrew Schultz style, and the game is polished.
