Went to the Berlin Indie Game Jam last weekend, a meetup of game developers. Made four games, three of which aren't awful.
5 hour jam, theme "album cover of your choice": Resistance Revolution
3 hour jam, theme Free/Cat: Feline Feeling
2 hour jam, theme Mysterious/Enemy: Mysterious Sniper
3 hour jam, theme Delicious/Suicide: Delicious Cake (don't bother with this one)
Resistance Revolution is my favourite of these, it was based on this Muse cover:
A quite satisfactory weekend. Met lots of cool people.
