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

[Deep One]

I think healing system is too simple in Amnesia and Penumbra, you simply click on laudanum or painkillers and your wounds are gone. So how about this:
If your hand is wounded, causing you to lose blood, press a button to enter healing mod. Then you would look down and click the hand which is wounded, and character would bandage it. And there should be different medicines for different wounds, like antidotes for poison.
