Done a bunch of game jams since my first ludum dare over a year ago, so much fun it turns out they're sort of addictive.

Will try and aim for something thats actually fun to play, always somehow seems to be less obvious than it should be.
Looking forward to the jam and to playing through everyones games afterwards.
Good Luck!
