Buy Nientum: Opus Zero Steam Key

Nientum: Opus Zero is a 2D action-adventure where the story unfolds through musical interactions. Two girls, Aleph and Liora, awaken with no memory in a forgotten theater, where a beautiful yet eerie stage and the secrets of the abandoned venue await them.

The gameplay loop centers on running backstage while hitting notes with two-key inputs in time with the performance, with player choices determining which ending they reach across 10+ chapters and 30+ tracks. The game blends platforming, runner-style action, and rhythm-based mechanics into a theatrical adventure. Nientum plays like a run-and-tune rhythm action game where timing is everything—as Aleph, you dash through stages while tapping or hitting notes in sync with the dynamic soundtrack to restore musical cues and trigger story events, with the simplicity of using just two keys requiring timing and precision, especially in later levels.

Unlike conventional rhythm games filled with intimidating note patterns, Nientum: Opus Zero focuses on the joy of interacting with music rather than difficulty. The game follows two amnesiac girls, Aleph and Liora, as they explore a massive theatrical world where distorted memories manifest as broken performances, with players restoring stage plays inspired by familiar myths and fairy tales including The Wizard of Oz, The Tale of Princess Kaguya, and Cinderella.

The main story runs for 12+ hours. The game features full Japanese voice acting with Chika Anzai as Aleph, Yuki Takada as Liora, and Takehito Koyasu as Mordred, and supports Japanese, Korean, English, Simplified Chinese, and Traditional Chinese text. The game previously received the Excellence in Audio award at Busan Indie Connect Festival 2024 and placed second in the Audience Choice Award at gamescom asia 2024.
