"What does work pretty well is the whole mechanic where a door won't open until you find a rune in the nearby environment by standing in a specific spot and looking at, say, a tree, a fencepost, and the post-mortem erection of a staggeringly well-endowed corpse so that they line up into a rune shape, That's a very fitting gameplay mechanic for the theme, because that's basically a sign of paranoia -- interpreting secret meanings and significance where none may truly exist, like when you hear a dog barking and take it as an instruction to gun down your neighbors (presumably given in a Scooby-Doo voice)."
