I used a couple of "called by other action" as resets for the interface & scene. One of the conditions determines whether interface is active so it knows whether objects can be clicked or hovered over or not.
I found the window (free template) & hallway scene on deviant art.
R key resets the scene providing the interface is turned off. Esc Key quits the game.
