Just offering a further suggestion if you did make the collider closer to the building after clicking on the door a message could pop up hinting at the real life building. Would be cool especially if it used the voice acting.
Not quite sure what the ending is! once I got to the skull walled area I followed the right hand wall and came across the scare and reset. Followed the left hand wall and was scared again and figured I had came to the end. Was there more?
