hmm, makes me think of a zelda Guitar Hero game. Now that would be weird
That would be simultaneously retarded and excellent at the same time. I think an Ocarina Hero would be cool...no wait, no it wouldn't.
No wait yes it would.
I thought of a Zelda music game with the different transformations from MM around 6 years ago.
Looking back it wasn't a very good idea, but I'd still play it.

I might give this a shot later if I have the time and feel like it.
