Our take on Promise with My Sister

Rather than centering its RPG structure on direct combat, the game makes exploration and sister development the main activities, with battles handled automatically. Progress also carries through memories and later rounds, placing relationship-building alongside route selection and team formation.

What is Promise with My Sister?

This RPG follows a brother protecting his sisters while recovering memories of their time together.

Players explore multiple stages, recruit sisters into a team, and develop each character according to her personality and abilities. Different routes and strategic choices lead through varied areas, while events strengthen relationships. Items can improve sisters, and some can be placed in the environment to alter exploration rules. Memories collected during play unlock items that strengthen sisters in later rounds. Battles run automatically, leaving exploration and character development as the main activities. Keyboard controls support movement through WASD or arrow keys, with mouse clicks for additional actions. Fast-forwarding and auto-save are also included.
