Choose a name and start the game! knock then trip asks you to come in, then Put your back against the grey bit near the door. then you will be outside of the map.. so when your out of the map, Walk along to the window and you can see trip and grace. then walk to your left and follow until you see a little gap, walk inside of it and you will find the outside of the elevator, click on the button and it will make a BEEP sound. then you will leave the game! its a simple trick that can be apart of the ending! enjoy.
