Intricacy is a game of competitive puzzle design. Players design "locks", and
try to "pick" the locks that other players have designed. The core lockpicking
game is a discrete-time-and-space abstraction of the mechanics of levers and
springs - in the same genre as XOR and its ilk, but quite distinct. It looks
like this:
.
A metagame provides motivation for designing and solving the puzzles; the game
this is most similar to is The Castle Doctrine, but Intricacy's metagame is
quite different as a result of being designed to be invulnerable to
sock-puppet cheating.
The first public release was nearly two years ago, and I've been
intermittently polishing it ever since. I think it's now in a pretty good
state. It's had a handful of players, a few of whom got quite into it, but it
would be great to have some new players and hear their criticism.
It's written entirely in Haskell.
