You find a note in your bedroom. It's from Mom. "My sweetie.. You're back home safe. But you've got to follow every single word to stay alive. THIS NOTE IS YOUR LIFELINE, got it? First thing, lock the big door and the bathroom door, so no creature can get it. Use newspapers to cover all the windows. Block that light like your life depends on it. BECAUSE IT DOES I have left a red doll for you. Keep it close. Don't let it wander away from you. You have to remember to knock on the bathroom door before you open it. Then, ONLY THEN, turn on the light. Don't open the door right away. If you spot a dark shape, kill the light, grab the doll, and run back to mom and dad's room. Close that bedroom door too. Finally.. SURVIVE." Day 1
