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.

Thanks for sharing this. Too abstract of a game for me, but I am impressed by the idea and implementation!

Looks well done. Releasing it for handhelds will make you a lot of money, especially if you add some popping-out graphics effects.

Although I heard Haskell runs horrible on phones, due to the lazy evaluation coupled with immutability making heave load on the garbage collection. I.e. GC becomes even less predictable.

Thanks. I assume it would run on a handheld with Real Linux installed; it just uses SDL for display. I did look in to porting it to Android, but it seems to be a bit complicated (and rather silly... you have to wrap everything in java??). The client isn't at all resource-intensive, though, so I expect it would run fine if it could be got to run at all.

A Ubuntu Touch port would probably work then
