At its core, 23 Sisters blends traditional text-based decision-making with resource management. You play from the perspective of an outside investigator (or, depending on the route, one of the elder siblings) attempting to prevent the family dynamic from collapsing.

The game originally began as a highly ambitious conceptual VN, which even spun off a short web novel companion. Managing a cast of 23 unique heroines presented major developmental hurdles, particularly regarding asset creation and render times.
