A game of competitive puzzle-design.

By ruthlessly guarded secret arrangement, the council’s agents can pick any lock in the city. A secret guild produces the necessary locks - apparently secure, but with fatal hidden flaws.

Coordinate a pair of lockpicks in a mechanistic turn-based puzzle game; construct intricate locks of your own to protect the secrets you discover.

Free software, released under the GPLv3.

Written in Haskell, with SDL and Curses user interfaces.
