It's good.
The display is awesome, I like the music too. For game play, well, it's almost the same as Miracle Nikki, so I guess it's just OK. The costume sets maybe haven't really piqued my interest (but I still try to get them). I like the characters though (the boys there are lovely 💜 I wonder if Hael has his UR). I recommend this game for those who want the doll-like character (it's 3D aight~) and nice music (okay, not all of the music, but most of it are nice~! ).
P. S. Nikki is the only 3D chara, you'd be in 2D set in the story 👌🏻
