Murder mystery visual novel built around escape rooms and branching paths. You're Junpei, trapped aboard a sinking ship with eight strangers, forced into a deadly game by a masked captor called Zero. Progress means solving point-and-click puzzles in numbered rooms—decode ciphers, manipulate machinery, find keys. Between rooms you make dialogue choices that determine which characters you trust and which doors you can access. The full story only emerges across multiple runs; early playthroughs answer some questions while burying others deeper. Each ending reveals a fragment, and the structure demands you piece together timelines yourself. It's dense with pseudoscience theories and requires patience for long text sequences. If you want a mystery that withholds answers until you've earned them through repetition, this delivers.
