More like it's a mashup of BEMANI games
One of my friend says it takes inspiration of only SDVX and CHUNITHM, but I think it's more like SDVX, IIDX PENDUAL, Reflec Beat, and MUSECA crossed together into one single game.
For songs, Shades of Light and Lost Civilization easily becomes my choice of best songs in the starting pack, Lucifer is also good. And surprisingly there's GOODTEK in there, which is okay. I haven't (and maybe couldn't) buy the DLC one.
