Among some doubtlessly good things about this game, there are quite a few music genres present, so if you like at least some type of Asian music, you’ll also find something you like here. Animation and graphics are done nicely.
I’ve heard from many people that “there’s too much going on on the screen”, which can be distracting for some people, but honestly once you get in a flow it’s not bad at all.
The amount of free songs is limited, but there are some events that give you access to more.
The biggest disadvantage for me is that the game is not optimized for the thumb playing, and you can only go so far without using more fingers.
