What new features would you add in a non-Amnesia Frictional Games Adventure?

[The Rock Worm]

Any way the one thing I want to see in the new game is more motion blur.

That would be good. It can be for both when you are moving/falling fast and when you get more and more insane.

Feature 13(?): Have things that psyche you out, i.e. you think you see something in a dark corner but it turns out to be something ordinary, like a fan.

That would be very good to have! It would certainly freak people out and keep them on their toes.
