I liked it, but...
Okay, the concept was great. I might suggest you add more songs, like the forest temple song from OoT(that one was my favorite), but also, it seemed that the arrows didn't go with the music.. They just seemed random to me. Gaves like DDR and guitar hero the arrows/buttons always correlate in some way with the beat or rythm of the music. Although i find both of those games extremely gay, i think that concept would fit incredibly well in this particular game.
So just add more songs, and make the arrows fit in with the music better.
Other then that it was a great game! :) keep it up.
