Last week I took part in this little event. Kind of a game jam in which everyone makes a contribution to the ideas behind every other entrant's games.
I think my game was a bit too big for the time I had to work on it, so I'm not going to crow about it yet. It needs a fair bit more implementation, although it is basically playable as it stands (just a bit sparse and buggy as well).
Expect a proper release some time over the next week or two.
