Same problem here. When I escape the cave (at the beggining of the game), the dialog box appear, the animation start, the music play and then.... nothin happen... The screen is lock (no HUD) and cannot click on anything.
Quite disappointing....
I'm running the game of a mac (yosemite, macbook pro mid-2013). I can provide more information if required.
I would like to know if this is going to be fixed in the upcoming patch. Would also appreciate a reply.
Thanks you.
