Our take on Quantum Suicide

Rather than using conventional dating-simulator points or flags, the story branches through character deaths in a recurring survival game. Reaching the true ending also requires both protagonist genders, making replay structure part of the narrative design.

What is Quantum Suicide?

This science-fiction visual novel follows a researcher aboard the Everett, an intergenerational spaceship seeking a new home for humanity.

A corrupted AI forces the crew into a weekly survival contest called the Deletion Game, where choices can create alliances, rivalries, romances, and character deaths. Narrative branches depend on who survives rather than on a conventional point or flag-based dating system. Players can choose a male or female protagonist and pursue seven romance endings, including three male options, three female options, and the AI. The game includes more than 30 endings, English and Japanese text with full voice acting, and an original soundtrack. Playing both protagonist genders is required to reach the true ending.
