The game crashes consistently when I reach the top of the damn to retreive the ammo. I'm playing the Linux build. Such a shame too because this game is wonderful! To be specific is crashes as soon as the words "I see what you're doing up there!" appear on screen.
Oh damn, sorry to hear that. Did you quit and then continue at some point? I think there's a bug with continuing games that I still need to fix, it could be that.
