Nientum: Opus Zero

Nientum: Opus Zero is a 2D action-adventure music game that combines platforming, action and adventure. You play as Aleph and Liora, who have lost their memories and take on the roles of Director and Actress in a silent theater. Through musical interactions, you prepare its stages and help bring the theater back to life.

The theater and its story

The theater was once filled with songs and stories, but now stands silent. As Aleph and Liora uncover clues in its beautiful yet foreboding setting, fragments of their lost memories emerge. Your choices shape what they discover and can lead the story in very different directions, changing their fates.

Tune the stages

Gems scattered through the stages are fragments of broken notes. Aleph can tune them, play their restored notes and repair stage devices as you prepare for performances. Platforming, puzzles and action combine as the theater gradually regains its vitality.

Musicals and performances

The performances reinterpret—and sometimes twist—familiar tales, including The Wizard of Oz, Cinderella and The Legend of King Arthur. Each time Liora gives a successful performance, more life returns to the theater, and the pair’s journey moves on to the next act.

Music and voices

The soundtrack features music by Kagetora., Halv and seatrus. Aleph, Liora and the other main characters are voiced by performers including Chika Anzai, Yuuki Takada and Takehito Koyasu.

Additional modes

The Director's Room lets you record and view collectibles gathered while completing the play. Free Play Mode offers tracks separate from the main story, built around Quesera Games’ rhythm-action expertise.
