I haven’t found a sticky for game jams, so I post it here.
Librejam (https://leagueh.xyz/en/librejam/) is a game jam for libre games (so open source code and assets).
It will start on April 1st and last for 7 days, which is quite convenient to whip up something quick.
I have partecipated in the first edition (202012); as soon as realised AGS is effectively free software too I thought "maybe other forum members can be interested too".
