The mechanic is pretty unique and super interesting! I'm kind of surprised it's a 2009 game, it feels... a bit older in its presentation. It still deserves a couple hours' play if you're a Rhythm Game fanatic, the hard mode seems really tough! I do wish you could set it on hard from the outset, because by the time I unlocked it I was ready to stop playing, and unlike say Elite Beat Agents you don't really have an addictive licensed soundtrack to boost replayability. I do love classical music, but on the tinny DS speakers... it's not the most pleasant experience. All in all, I think there is untapped potential in this.

Oh also the boss battles are just boring which is a pity! At least they don't take that long.
