Interesting feel to the song. I like the water, it's a nice touch, as you don't often hear sound effects used in MIDIs (at least, I haven't). The background does get a bit repetitive, but that's mainly because there's a lack of a distinctive chorus of sorts, or at least a bridge. Perhaps add something in that is a change of rhythm. I like the nice shift into a darker tone later in the song, then the gradual change back; it adds some colour there. Overall, well done, a good and solid track, that's fun to listen to as well.
