How Many Secrets Under Ceiling

How Many Secrets Under Ceiling is a light novel-style deduction game about a locked-room death. A mysterious girl arrives at your detective agency offering to be your unpaid assistant, and a sheriff brings you a case: a resident has been found dead in a room with its doors and windows sealed. You investigate whether the death was suicide or murder and, if it was murder, which neighbor is responsible. The suspects include an approachable merchant, a carefree unemployed person, a naive actress and an intelligent salaryman. You also try to uncover the identity of the girl, who cannot explain her own origins.

Solve through dialogue

The game focuses on logical reasoning rather than physical evidence. You examine conversations and narrative details, using contradictions and loopholes to solve cases and decide who is lying. You play as yourself, making choices according to your own logic, preferences and values as you work through puzzles and dangers. The scenario is written by a new writer with the Gentosha Mystery Fiction Award and is based on The Walker on the Ceiling by Edogawa Ranpo.

Choices and endings

The game includes more than 25 personality options, more than 25 logical puzzles and more than 25 action options. A professional file and information summary helps organize the case details. Its 80,000-word script has five endings, and more than 30 illustrations can be unlocked.
