I like it! I've never played the series, but it's always been obvious that it's a light-hearted adventure through numerous locales that's meant to be simple, yet very enjoyable, and, really, I think this song captured that.
I also found the ending section a nice surprise, as it came rather unexpectedly. This is because the rest of the song was very fast-paced and got the blood pumping,but the end managed to be reflective of the serenity of the beautiful environment the game possesses. I imagine this was your intention, as it seems like the kind of game where you can be swept up in the excitement of the action that, when one of the quieter moments pops up, like wandering the desert, it's unexpected and surprisingly enjoyable precisely because it contrasted what you just experienced.
Keep it up!
