Level 65 of the farmhouse has a control panel with a button (and a sign saying "Do not touch with jelly fingers"), 2 doors, and a window letting in light from a sun (but not "the" sun). Opening the door on the left is forbidden. The door on the right is the "good door", and can be opened to any time and/or space by Thomas, who resides on and watches over the level.
