30-SECOND KNOCK
A Psychological Horror Experience
Every 30 seconds, something knocks at your door.
Look through the peephole to see who's there.
Real visitors are safe. Fakes will destroy your sanity.
Press E near the door to look through the peephole.
Press SPACE to open the door, or walk away to ignore.
Warning: Fakes become harder to detect as your sanity drops.
