This jam is now over. It ran from 2017-12-01 00:00:00 to 2017-12-17 23:00:00.
I recently wondered whether or not there has ever been a playable Christmas tree. To my surprise I couldn't find anything on Google, and my friends didn't know of anything either. They did almost immediately call for a Christmas Tree Game Jam though, so this is now a thing!
The plan is to have a few relaxed video chats or hangouts during the duration, the first one is planned on the weekend of the 2nd/3rd December!
