This is a brief, 5 room game with purposely minimal implementation.You find things like pits of binary numbers, syntax errors, and self referential rooms.

The puzzles are ridiculous, but there's so few items, you can just try everything. The solution to the main puzzle is based off a joke that the author used to tell to their friend.

Many people like this game, including me, because it's absurd and silly but has logical puzzles.
