Alright. All in my opinion of course.
As a videogame background theme: amazing stuff. I was excepting some crappy stuff but everything was right. The melody is enjoyable and really feels like it should be put right away in a videogame. The percussions are osom, really nothing else to say other than very well done.
As a song by itself: it gets boring after 3 minutes. You change the melodies a bit, but you don't change the general structure, so it's basically always the same just with different notes. But who cares, this was probably meant to be a videogame song so...
4½ / 5
