As flawed as this game may be, I can't help but be charmed by how it looks & feels. The visuals, song choices, gameplay & probably some other things that are part of this game are just so "cute" & "nostalgic" that I can't help but be enamoured by this.
Quality-wise, I'll have to give it 3.5 (kind of easy & small character roster, but the gameplay of it is interesting & the music here is genuinely great), but it'll always be my favorite 3.5 to ever exist, probably ever.
