I'm going to give my thoughts here.
it's a 2/5 in my opinion, and let me explain.
It truly is a novel concept, but the rhythm is all off. Using tones when you hit the notes makes songs unrecognizable. there's no reason not to just blindfire shoot instead of following the pattern due to a lack of a score based on when you hit the note.
It needs plenty of work. I didn't hate it, but it wasn't fun.
