The game is really well-polished in terms of aesthetics and music and overall integration of soundtrack into gameplay etc -- but it was extremely difficult for myself as someone who's not used to rhythm games at all. Some clearer explanations, and/or a written-out tutorial would have been very helpful. It's especially hard working with different direction inputs for each hand at the same time (I would assume this would be expected at much more advanced levels than only a few minutes in, if this was a full-length game). I ended up giving up at the last lock. :(
