There's something about this that sets it apart from what I typically define as 8-bit music. It might be the bass, but whatever it is it feels like there's a certain depth to this track that 8-bit doesn't traditionally have. Maybe it's a range of tones, I really have no idea. Apart from the not-fully-traditional-8-bit aspect it sounds great though, smooth and ambient, varied; continuous.
I'd like the alternate melody (the one that plays around 3:20... and probably at earlier instances) to be a little more in the foreground, and a bit more melodic somehow. It's nice though, keep it going!
