Through a phone camera at night: a dark hallway, lit only by a phone lying on the floor. At its far end, a door is being traced in thin gold light.
FILE 01 · REC
Thirteen doors. They only appear through glass.
Behind the last one is whoever made them.
Headphones. Night. Alone.
Best with headphones · plays even in silent mode
I knocked.

FILE 02 · 03:03
A horror mystery you play through your phone’s camera, in your own room.
One door opens each night at 3:03 AM.
Each door is a chapter of the story, and seven things to do through the camera. Six of them give you a piece of what the seventh asks for.
It’s 3:03. There is a door in this page.
Something knocked back.

FILE 03 · HER PHONE
Lena Ostrova was the first to reach the last door.
She was nineteen. She played every night at 3 AM, in the bathroom, with the lights off.
They found her phone on the floor of an empty church in Valparaíso, screen still on, camera still open.
Nobody found Lena.
This is all she left.

FILE 04 · THROUGH THE GLASS
About thirty ways to play through glass.
Tilt it, cover it, knock with it, hum to it. Each door asks for something different, and it only works in a real room. Here are six.
-
Tilt the glass.
Drag, or use the arrow keys.
-
Cover the lens.
Press and hold.
-
Knock on a real door.
Click or tap to knock.
-
Hum.
Press and hold.
-
Turn the glass around. Your reflection is late.
Move, then wait.

Don’t move. It only sees what moves.
Press the button, then keep still for six seconds: no mouse, no keys, no scrolling.
Ready when you are.
Camera frames and the microphone never leave your phone. No account. No uploads.
A horror game: sudden loud sounds, flashing images.
It’s behind the glass.
FILE 05 · THIRTEEN DOORS
Thirteen doors. Thirteen nights.
Each door is a night, seven objectives, and one line of her note. You start with the first line. The rest is still dark.
DOOR I · THE MAZETILT
“Every room hides a maze. It keeps three embers. Give the door their numbers in the order the eye looks at them.”
OPEN TONIGHT · 03:03
Hover, focus or tap a door.
