Nientum - Op.ZERO launches with its full story and 30-song rhythm adventure

Nientum - Op.ZERO is now out on Steam and Android, bringing its full musical story to a rhythm-action adventure about two young women trying to revive a forgotten theatre. The game launched out of Early Access on 14 October, with its iOS version still planned for a later date.¹

A theatrical rhythm adventure

QueseraGames’ game follows Aleph and Liora, who have lost their memories inside a silent theatre. Aleph takes on the role of director while Liora performs on stage, with chapters reworking familiar stories including The Wizard of Oz, Cinderella and Arthurian legend.¹²

The full release adds chapters six to 10, a post-story chapter, a collection room, scene skipping and Hard difficulty for story songs. Free Play also expands to 30 tracks, while the main story contains more than 10 chapters and is expected to take over 12 hours to complete.¹

Steam describes the game as a 2D action-adventure that combines platforming, puzzles and musical interactions. Its store page also confirms English, Japanese, Korean and Chinese language support, with voice performances including Chika Anzai, Yuuki Takada and Takehito Koyasu.²

Launch details

The PC version is available through Steam, while the Android edition is also launching today. The game is listed at ¥2,200 in the Famitsu report, with a 20% launch discount running until 28 October; iOS remains marked as coming later.¹

Our opinion

A full story launch is a much better reason to look at Nientum - Op.ZERO than its Early Access status alone. The combination of stagecraft, rhythm play and familiar tales gives QueseraGames’ indie adventure a clear identity, while the new chapters and expanded song list make this a meaningful 1.0 rather than a cosmetic label change. The unusual theatre setting is doing a lot of the heavy lifting, but that is precisely why this is one to keep on the radar if you like rhythm games with a proper narrative spine.
