About this game
This game contains some light surprise elements, but no grotesque imagery or violent scenes.
Nevertheless, it offers a strong sense of gloom and unease fitting for a horror experience.
It’s a recommended “intro to horror” game for those who are curious about horror but don’t like overly scary content, or for children to enjoy safely.
Synopsis
Driven by the dream of making a fortune through vacation rentals, you purchase an old, secondhand apartment building.
However, an abnormal situation unfolds as guests begin disappearing one after another.
Determined to uncover the cause of these strange occurrences, you thoroughly investigate each room, only to face the wrath of discarded leftovers and their lingering grudge.
Game Rules
Your goal is to escape from the mansion, but standing in your way is "leftover food."
By eating leftovers, your stomach level increases, allowing you to consume even larger portions. Efficiently leveling up your stomach is the key to escaping.
To support your exploration, items that enhance your senses, such as smell and vision, are available. Additionally, an auto-mapping feature is included to prevent you from getting lost, ensuring a comfortable gameplay experience.
Will you be able to escape from this harsh mansion safely?
