This game looks like sound voltex booth and plays like tap sonic. Its basically another scrolling notes beatmania clone, but its not a bad game. It has Kpop, vocaloid, and EZ2DJ songs, but most you have to pay to play. The worst part is that it is all in Korean, so it can be difficult to navigate menus and such.
