My group’s entry for the 2012 Game Jam was called Eternal Guardian. It can be found on the Game Jam’s website. It was made with PyGame, so it works on any platform that supports PyGame: Windows, Mac, Linux and most Unices.
The theme this year was the Ouroboros, the serpent that bites its tail. We made a game on the theme of sustainability and renewal. A Mayan city in peril is granted the help of the snake god from the incoming peril. But protecting the city is not as straightforward as it seems.
As this was made for the Global Game Jam, the whole game, art included, was made in less than 48 hours. Programming was done by Daniel Langdon, Andrew Sweet and me. Daniel was great at solving what turned out to be very tricky math problems. Andrew as our local PyGame expert. I took care of the sound. And all the art was done by Jame Threefoot.
