Full Release, Steam, and Android
Chapters 6–10 Bring the Story to Its Conclusion
The largest addition in the full release is Chapters 6–10. These five chapters carry Aleph and Liora's journey to its main conclusion, finally allowing Early Access players to reach the last curtain.
QueseraGames has also added and enhanced presentation across the story, including previously released chapters. Since player choices can redirect the ending, the update completes the narrative structure that has been central to Nientum from the beginning.
Rhythm, Platforming, and Musicals Share One Stage
Nientum does not isolate its rhythm mechanics inside a simple song-selection mode. Players move through backstage spaces using platforming, puzzles, and action before entering musical performances.
Through Aleph's Tuning ability, broken notes and stage devices can be restored. Familiar stories including The Wizard of Oz, Cinderella, King Arthur, and Princess Kaguya are then reinterpreted as musicals inside Nientum's theater.
Free Play Now Contains 30 Tracks
The full release adds 20 new tracks, bringing Free Play to a total of 30 songs.
Contributors include Sakuzyo, Street, Team Grimoire, Ice, Sennzai, Nanahira, Kagetora., Halv, seatrus, and seibin & Mitsukiyo. Free Play operates separately from the main story progression, allowing players to focus directly on the rhythm charts.
Android Launches Alongside PC, iOS Still in Preparation
The Android edition launched alongside the full PC release. Google Play lets players experience the opening chapters for free before unlocking the full theater through a single purchase.
QueseraGames is still preparing the iOS version and has not announced a launch date. By October 18, Android had also received additional fixes for touch input, frame rate, and difficulty selection through patch 1.0.13.
Why This Matters
1) The full release actually completes the story
Chapters 6–10 are not side content; they bring Aleph and Liora's central narrative to its conclusion.
2) Music is part of both the world and the mechanics
Platforming, Tuning, performance sequences, and boss battles all revolve around music rather than treating it purely as background audio.
3) Android significantly expands access
The mobile version launched alongside the complete game and offers the opening chapters free before asking players to unlock the full experience.
