The case

Mary Doyle was the only adult in the building.

After that night, Mary vanished. She took the youngest resident with her: four-year-old Stephen.

Thirty years later, Mary died. She left behind a box, a letter and one request: take the box back to the orphanage.

In 1911, Father Thomas Ward opened a book on this hill and something answered. There were seven of them, one for each deadly sin. He bound six. When he called the seventh, his hand shook.

One of the six is not like the others. It talks. It persuades. It helps.Father Thomas Ward, last note

Gameplay

Light is a weapon. Darkness is an enemy.

INVENTORY

A bag that takes up space

Your bag is a grid. Every item has a shape. The flashlight, the bat or the ritual candle: something always gets left behind.

ULTRAVIOLET

Only the light touches them

A bat or a thrown chair stops the Soulless. The ghost children fall only to your flashlight's UV mode, and the battery runs out.

PUZZLES

No menu to hide in

You turn the symbol lock while standing in the room. If something comes up behind you, you turn and run.

RITUALS

Close the seals by hand

Free the caged candles, light them in order, draw the sigils yourself. An unfinished ritual does not kill them. It angers them.

MIRRORS

Mirrors are doors

Stand before one with the right object and you cross over. You come back, but not as the same person.

THE VOICE

Choose your question

A voice on the radio guides you. You decide what to ask: what should I do, or who told me to do it?
