The freeware Indy fan game, Indiana Jones and the Fountain of Youth, has just released a playable demo. FoY is made with the Adventure Game Studio, a software for creating point-and-click adventure games. Though it is not open source, it has a Linux port (and also FreeBSD), and it works with FoY as well.

I’m currently stuck in this demo, however, I really can’t wait till its full version release :)
