This jam is now over. It ran from 2019-12-26 04:00:00 to 2019-12-31 22:59:59.
This year's theme is "Between lights and shadows".
You can use that for your game's mood, mechanics, aesthetics, anything actually !
There are no prizes to win, the games are not even ranked and no one will play them. So why join ? Meh, no real reason except learn a little bit about making games and have fun so go away now if you're doing this for anything else.
