About This Game

Preparing the stage for the performance is an important part of the gameplay. Controlling Aleph, you explore locations in search of scattered gems, which represent broken musical notes. Using her abilities, she tunes these notes, bringing the theme music to life and restoring props that have lost their purpose. This process in Nientum OpZERO is necessary for the curtain to finally open and the performance to begin.

When the stage is set, Liora steps in, tasked with successfully completing the performance. The theater's repertoire includes musicals based on such works as The Wizard of Oz, Cinderella, and The Legend of King Arthur. Each successful performance by the actress brings vitality to the theater. Despite the seemingly distorted plots of the productions, the heroines manage to improvise, steering the story toward a hopeful ending. Collectors can enjoy a director's room, and they can hone their skills in the rhythm-focused Free Play mode.
