My kid came home and told me he had played the scariest game he ever played before,
Penumbra he found a movie for the beginning of the game quite cool it seems.

I gave wrong URL and the game is

Penumbra "Black plague" and it has a very nice physics motor.

Overture works great in Linux too, Ill probably get Black Plague as well once they finish porting it.
