In this house (single-player only works best!) you have a sweet basement with a kitchen, wood stove, and fireplace. Go down the long hallway and press the button to get out through the basement of the house. The button uses a t-flip flop (for info, go to Youtube.com and search ghostyx123) so that you can press it once and the door stays open. Press the button on the other side to close it.
Enjoy!!!
