I'm having trouble playing "Sherlock Holmes: The Awakened Remastered." When I'm in the asylum lab as Sherlock, I can't crouch down, and keep getting caught by the nurse. I have the walkthrough, and it says to press "Ctrl", but the "Ctrl" key only changes between 1st and 3rd person perspective.
I'd like to play this game, but am stuck at this point.
Any help would be appreciated.
