Please post all your bug reports here with screenshots, your PC specs and a crash report if you get one.

Devs, you have to fix that asap.

I keep trying various things along the above-ground route, but I'm not getting anything at all. Can anyone at least give me a hint? The tail end of the path is the same when the paths remerge, right?

There is no way to exit the game. Command-Q does nothing. Escape crashes the game, which is a sort of exit, I suppose, but no achievements are credited. I also have zero Steam trading cards from a half dozen play-throughs. Mac OS X 10.11.2

In the game there is no way to take a screenshot using the F12 =(
