Wonderful game, would recommend.
The only thing I criticism I have is the AI. Frankly, given how sussy the scenario is, I think most players would be okay if the AI "cheated". But I'm not asking for that.
In my playthrough, I thought the AI would count bullets (because it happened to choose the right options), but when I got my friend to play it, the AI shot itself when there were like 3 live rounds and 1 empty round! That kinda-dumb move completely took me and my friend out of the suspense/atmosphere!
