Amazing.
I love that tune to death. I could listen to it forever. Not only is it beautiful and catchy, but it's so nostalgic it hurts. That was the first video game I ever beat, and I hummed to this song for probably over 100 hours. Hearing it in 8-bit is refreshing, yet familiar. Great job, by the way. Even though it's not jump-out-in-your-face-bass or laden with heavy beats, it still hits the spot just right. I can also tell it took forever, so kudos.
