Well they seem to have kept this quiet. 96 hour jam but only 2 hours remaining. Heres what it is about.
Nine development teams from around the world and one solo developer have volunteered to create games and raise money to fight ebola. These generous indie developers include Grapefrukt, Ludocity, Glitchnap, SLMN, Coffee Stain, and three teams from Mojang. Plus, TheMogMiner will be contributing as well! Donate an amount of your choice, and you'll get all of the games created during the event after its conclusion.
