About This Game

"—To fade away... is it hope or despair to you and me?"

[Nientum - Opus Zero] is a 2D action game that combines platformer, runner, and RPG elements with musical interaction.

A theatrical tale of two girls who have lost their memories, set on a beautiful, eerie, and sorrowful stage, with secrets hidden within the theater awaiting you.

Prepare the Stage with Dynamic Actions

The gems scattered throughout the map are broken musical notes. Use Aleph’s abilities to tune the broken notes, restore the stage props, play the music, and get ready to open the curtains!

Complete the Performance on the Prepared Stage

Musicals featuring tales such as The Wizard of Oz, Cinderella, and The Legend of King Arthur! As Liora successfully completes her performances, the theater will regain its vitality. Though the plot of each play seems twisted, our protagonists somehow improvise their way toward a hopeful, happy ending…

And Uncover the Truth Behind It All…

Nightmares, longings, frustrations, and hopes—new encounters and farewells

""Aleph"" and ""Liora"", having lost their memories, take on the roles of stage director and actress. Together, they delve into the secrets hidden within the theater through their performances.

One by one, clues are revealed, leading the two girls to uncover the hidden stories about themselves…

Your choices will determine their fate.

Join them in their great journey.
