Korea’s rising indie studio Quesera Games (CEO Jaehyun Park) has announced that its new 2D action-adventure rhythm title, “Nientum – Opus Zero,” will launch on Steam Early Access on November 24. The game blends platforming, runner-style action, and rhythm-based mechanics into a theatrical adventure that has already garnered significant anticipation.

🎵 From Hit Rhythm Game ‘KALPA’ to a New Genre Fusion
Quesera Games entered the industry to become “Korea’s premier rhythm-game studio.”
Their debut title KALPA, established that identity early, recording 1.5 million downloads as a traditional mobile rhythm game. The PC port—funded through a successful crowdfunding campaign—also launched on Steam Early Access earlier this year, accompanied by a ₩130 million ($95,000) Tumblbug campaign.
Building on this momentum, the studio aims to redefine the rhythm-action genre with Nientum – Opus Zero.

🎭 A Rhythm Game That Doesn’t Look Like a Rhythm Game
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. Players must restore stage plays inspired by familiar myths and fairy tales—including The Wizard of Oz, The Tale of Princess Kaguya, and Cinderella.
CEO Park notes:
“We wanted people to enjoy the act of interacting with music without feeling overwhelmed by traditional rhythm-game complexity.
Our biggest design challenge was building a rhythm game that doesn’t instantly look like a rhythm game.”
🎬 A Play Within a Play: Musical Staging Meets Action
The game alternates between two layers:
1. Backstage (Platforming Exploration)
Find and tune “broken notes” scattered throughout each stage while navigating a whimsical sidescrolling world.
2. On Stage (Real-time Musical Interaction)
Players manipulate stage machinery in sync with music, completing theatrical performances in real time.
Movement is automatic—notes appear left and right on the track, and players “jump onto the rhythm” rather than pressing falling notes.
Later chapters escalate to dramatic musical boss battles, framed as vocal duels that heighten narrative tension.
The overall presentation blends papercraft-like art, musical spectacle, and side-scrolling action to create an audiovisual experience unlike any existing rhythm game.
