Psycho-Sleuth Demo
PHOSEPO · released Sep 25, 2025
Psycho-Sleuth is a mystery game where cognitive disorders distort the rules of murder. 13 players, each with a strange condition — like “no lying,” “no left side,” or “no faces” — are trapped in a deadly game. These disorders are contagious, and the killer hides behind abnormal logic.
