After playing The Cave for several minutes (half an hour?) the option for "Save and Exit" disappears from the menu, and the last menu item is "Drop Character" (which doesn't do anything). See the attached picture.
When I play the game for a very short time, the "Save and Exit" option is still there. I exit out of the game, don't close steam (the steam icon is still in my tray), and restart the game. If I press escape, I see "Save and Exit" is still there. It's only after playing for a longer time that it disappears.
It might be related to finding cave paintings. Maybe the option is still there before I find the painting, but not after I view it? I'll have to play around and debug some more.
I'm running The Cave through Steam on Linux Ubuntu 12.04. The machine is a Sandy Bridge Intel graphics system, running the latest Mesa master branch (as of 2013-04-11).
The only thing I did besides just install the game was add my wired USB XBOX controller to ~/.steam/steam/SteamApps/common/TheCave/Data/Config/SDLGamepad.config:
030000005e0400008e02000010010000,Microsoft Xbox 360 Gamepad (xpad) (Linux),a:b0,b:b1,y:b3,x:b2,start:b7,guide:b8,back:b6,leftstick:b9,rightstick:b10,leftshoulder:b4,rightshoulder:b5,dpup:h0.1,dpleft:h0.8,dpdown:h0.4,dpright:h0.2,leftx:a0,lefty:a1,rightx:a3,righty:a4,lefttrigger:a2,righttrigger:a5,
Anyone else have a work-around for this?
