Key features

Rhythm scoring wired into a card system

Cards modify how charts are scored rather than sitting in a separate menu. That means a run is planned before it is played, which gives rhythm players something to optimise other than raw accuracy — the usual ceiling that pushes people away from the genre.

Five protagonists sharing one timeline

The narrative runs through five characters whose stories intersect. Rhythm games normally treat story as a wrapper you skip; structuring it as intersecting perspectives gives a reason to play charts in a particular order.

From the Arcaea studio

lowiro built Arcaea, one of the most-played mobile rhythm games. The relevance is chart design: the studio has years of published difficulty curves behind it, which is the part of a rhythm game that cannot be faked with presentation.
