I have to disagree with TaintedLogic on one point. Probably the best aspects of this piece are the perc lines, which add the most drive and motion. It's otherwise VERY repetitive and lacking in satisfying chord resolutions. Can't add much more than that. It's a very simple, rudimentary piece with very little in the way of harmony or motion. This lends to an empty sound that fails to keep my interest for very long. At the same time, it would be appropriate for a very minimalistic GBC styled game. Without visual elements of some sort, though, it falls flat and fails to really communicate an idea.
I did enjoy the piece somewhat, but critically, it falls flat. Don't let that deter you though. Keep at it!
