As some of you may already be aware, Mickey Mouse, or at least Steamboat Willie is in the public domain in the US. Why not use something old that entered the public domain recently and use some public domain music while you are at it? Of course don't be like those crazy horror films that only have old characters as a gimmick and nothing else, make sure to give it soul. I don't know exactly what I want to do for this game jam but I think that using things from the public domain could be really cool!
Happy Jamming
