This past weekend I took part in the Global Game Jam. It was an intense 48 hours of game making madness. My group had 5 members and we made a game called Sciencology, a battle between two rival scientists.
You can find the game here: http://globalgamejam.org/games/sciencology .
We started with really lofty goals, but managed to cut out just enough to make it work. Overall, I’m satisfied with the game.
