Military barracks escape

Needed the walkthrough (had to look up on Bing as the one "provided" in the game doesn't work) in order to get the hammer head. Figured out I needed to shoot the door, but it still took a bit to figure out how to actually get out once the door was shot up. 2/5 because things just aren't too clear in the game. It would help if the cursor became a hand when something is available to interact with/pick up.
