I am a big fan of Groove Coaster so this game is an easy fit. The songs are actually pretty numerous for a jam game and diverse too. It even seemed like there was even more music available on the menu. The charts matched the songs well, and being able to set my own calibration made it line up nicely. The overall presentation is great, and I like how the fairy character is the icon on the track.
However, I am going to join the chorus of people saying the notes cluster too much. It can be near impossible to see what is coming next, especially for a rapid series of inputs in the same direction as travel. And distinguishing between a short hold and a triple tap is difficult. The option to speed up the track would help a lot in pulling those clusters apart.
