I wasn't able to take much part in the Global Game Jam this year. Circumstances conspired to limit my involvement to transporting Hull students who wanted to take part over to Grimsby Institute, where the competition was held this year.
From the looks of things the competition went really, really well. Kudos to the Grimsby team for running an excellent competition. The winners of the event were Blimbu, who are Game Jam veterans and have been producing high quality games from the very first Global Game Jam in Hull a couple of years ago.
You can take a look at the game that they made in only 48 hours here.
