"Secret Glitch Level To find a strange secret level, load Part 1: Prologue or start a New Game. Follow these steps:
1. Check out the swing set to the left of the house. A small message will appear. 2. Enter the house and play the piano until a message appears. 3. Turn on the radio, located in the back room behind the garage. 4. Grab the flashlight. 5. Walk outside and look on the post across the street to find a missing person’s flyer. 6. When you get near the flyer, you’ll immediately die. It might take several tries to get this event to occur.
Back at the Main Menu, choose to start a New Game, and get ready for something totally different.
A message will appear: “I’m lost. Can you find me?” You’ll be able to explore the house in this glitched state. Don’t give up, there are three iterations to the stage. And they’re all surprisingly creepy."
I think you also need the newest update.
