This game is similar to David Welbourn's classic 69105 keys. You search through piles of keys divided by adjectives, trying to find a unique key. It includes some innovations over the previous game, including multiple game modes, a different kind of randomization, and an anti-game for finding the 'worst' key.
There seems to be a bug with the second half of the game that lets you instantly win, but otherwise this is a nice to game that goes from 'banging your head' to 'oh I see'.
