Playing Dance Rail, a mobile game extremely similar to Chunithm with simple and cleaner UI (depend on which theme you choose), customisable notes sensory (registration of notes such as “Very Easy” which make the registration easier by holding, or “Very Hard” which make registration to be precise when hitting the note), and some of the songs have special gimmicks to it such as one being a literal math quiz. This is just an outlines of the game but it’s a fun game to play in free times.

On an additional note, there’s a sequel called Dance Rail3 available, either play the original or the sequel.
