This weekend I took part in the seventh edition of the Global Game Jam. The goal of the event is to create a game related in some way to a given theme in 48 hours. This year's theme was What do we do now?.
Instead of flying solo, as I did last year, I joined two friends: Javi and Esteban. It payed off big time, not only because jamming alone doesn't make any sense (I can code by myself any weekend I so desire -- which is most of them), but also because I jammed in good company and we fucking won the local Barcelona section of the jam.
If you want a detailed account on how it went or some technical tips to play the game, I refer you to Javi's write-up. Other than that, here's the profile of the game at the GGJ web page and a link to the game. Enjoy!
(UPDATE) Here's the presentation of the game Javi gave at the end of the jam:
