Promise with My Sister (All Ages)

Promise with My Sister is a story-driven strategy role-playing game centered around a group of sisters and their protective brother.
Players take on the role of the brother, tasked with reclaiming the lost memories of time once shared with his sisters. Through a journey filled with exploration, trials, and strategic decisions, players will experience a deeply personal RPG adventure shaped by their own choices.

Inspired by the classic Tower of the Sorcerer, the game blends team-building, resource management, and route-planning mechanics.
Choose up to four companions from a diverse cast, allocate limited resources wisely, strengthen your team, and defeat fixed enemy formations as you conquer each layer of the map on your way to the final goal.
Every step requires careful strategy and planning, challenging you to find the optimal solution within strict limitations.

• Build a team of sisters, find the ones that suit you best.
• Sisters each have their own unique personalities for you to freely cultivate.
• Various exploration routes and strategies freely selectable, venture deeper to find more sisters.
• An abundance of items to enhance sisters, plus unique items that can be dragged into the scene to change exploration rules.
• Collect memories with sisters and unlock items, making sisters stronger in the next round of the game.
