Made it to the second floor, I have two keys and a wand but I have no idea how to get the door open. I've used the number keys to select one of the keys, moved the yellow rectangle over to the door but nothing happens when I press Enter. Ended up giving up in frustration unfortunately. I'm clearly missing something that may be obvious to others?
Hmm, the way to open the doors should be to press a number key corresponding to the slot a key is in, then moving the reticle over the door and pressing Enter or Numpad 5. Sounds like this is what you did, but if it's not too much trouble, could you try doing this one more time to confirm that something is broken?
