Answer the phone that is ringing. Wait for the door to unlock after the message plays.

Walk down the hallway and turn on the TV.
Read the torn newspaper note and make your way back into the hallway. Look at the family tree board.
Walk back to the TV and look closely at the screen. As you make your way back into the hallway, a closet will open with a key.

Grab the hammer and use it to remove the wooden planks from the door. Enter the room with the blue lights.

Stare at the gap in the door. After it shuts, attempt to open the door. Wait for the phone to ring, then answer it.

Make your way down through the hallway and grab the flashlight.
Interact with the bright red screen and wait for the light to start flickering. Eventually the light will die out. Enter the dark area then wait until the door is unlocked.

Try the door on the other side of the hallway. After the lights turn off, stare at the scattered notes until the door to your right creaks open. Look through the door gap while zoomed in.
Make your way around the room and enter the door. Listen to the message played by the TV. Exit the room after the message is done playing.
The rest is straight forward. Make your way through the rest of the demo.

You have completed the demo! Thank you for trying it out.
