About the game

一人称視点の心理ホラーゲームで、廃病院を探索しよう。鍵を見つけ、パズルを解き、隠された手紙を発見し、懐中電灯を管理しながら、Mariaの悪夢に隠された真実を求めて恐ろしい遭遇を生き延びろ。

Steamの原文説明

Maria wakes up alone inside an abandoned hospital, with no memory of how she got there.

The hospital is empty... or at least it seems that way.

To find a way out, Maria must explore the hospital, search its rooms, find keys, and uncover a series of mysterious letters hidden throughout the building. The letters must be discovered in the correct order, revealing subtle clues about the horrifying things lurking inside.

But the deeper Maria goes, the stranger everything becomes.

GAMEPLAY

Explore: Search the abandoned hospital, investigate its rooms, and look for hidden clues and important items.

Solve Puzzles: Use your surroundings and the clues you discover to solve puzzles and unlock new areas.

Stay in the Dark: Your flashlight is your main source of light. Keep exploring and make sure you have enough batteries to see what is hiding ahead.

Defend Yourself: Maria has no traditional weapons. A mysterious doll can temporarily stun the enemy, giving you a chance to escape.

The Pill: At a certain point, Maria discovers a mysterious pill that changes her understanding of everything that has happened.

Discover More: The hospital contains hidden details, secrets, collectibles, and an additional puzzle for players willing to explore beyond the main path.

STORY

The letters scattered throughout the hospital slowly reveal what happened and hint at the creatures hiding inside.

As Maria gets closer to the truth, disturbing events begin to happen around her. Some can be avoided, but only if she pays close attention to the clues left behind.

And when Maria finally discovers the truth, she realizes that the hospital may be part of something far more disturbing than she imagined.
