100 Seconds: Scary Horror Game

3:00 a.m. Above the door, a digital timer reads 100.
Something knocks three times. The phone rings, but the cord is unplugged. The clock stops. Under the door, the light is broken by two feet. In the mirror, someone is standing behind you.
All you have to do is survive until zero.

100 Seconds is a scary first-person psychological horror game set in a single room. Each night lasts exactly one hundred seconds, and each night the rules are different. Find them. Understand them. Obey them.

★ HOW IT WORKS
The countdown starts at 100 and runs through ten phases of ten seconds. Move with the left joystick, drag to look around, tap objects to use them. A presence is waiting, and it reacts to where you look, how you move and how close you get to the door. Reach zero and you survive the night.

★ THE RULES
Nobody explains them. You deduce them from the clues: a note in your own handwriting, words scratched into the wall, whispers, the radio, the messages on the timer.
• Never open when it knocks three times.
• Don't answer if the cord is unplugged.
• Don't look at it. The mirror is safe.
• When everything goes silent, don't move.
• When it walks in, the light must be off.
• If the clock stops, wind it.
Rules and clues change every night. Every death can be avoided, and the first time you break a rule nobody has taught you yet, it only warns you.

★ EVERY NIGHT IS DIFFERENT
54 events in the catalog, combined differently every night. Three modes: Normal, Nightmare and Randomized Nightmare, where rules can change meaning and rare events appear. In Randomized Nightmare you can pick a seed and share it, so your friends face exactly the same night.

★ THE STORY
November 3rd, 1996, 3:00 a.m. Someone knocked on your door using your secret code. You counted to a hundred before opening.
Why? Piece it together through 4 endings, 9 story fragments to collect and the tally marks on the wall that count every night you have lived through.
