Our take on Zero One / 杀戮世界

The likely sticking point is the choice-and-dialogue loop: players who expect choices to open up broader gameplay may hit a wall once they realize the main task is reading lines, inferring motives, and selecting replies.

What is Zero One / 杀戮世界?

Zero One is a short, modern-set mystery told as a text adventure.

Game maker Toyota Rei plans to kill the people responsible for her sister's death and then take her own life after they are released for lack of evidence. Honda Hajime, another game maker who is devoted to Rei, tries to stop her. The story advances through character dialogue and choices; responses affect which of four endings unfolds. The game is fully voiced and divided into multiple chapters, with a stated playtime of 1–2 hours. Its main interaction is reading, inferring what characters think, and choosing replies. The game also includes a small amount of graphic material.
