This song reminds me of when I started out! Piano-only, simple on-beat notes… brings back memories. As you might realize yourself, this makes it a bit simplistic, and the use of piano-only and the same on-beat notes really limits you in expressing the theme. I do like that the song gets progressively darker and louder, especially at 2:45 - this reusing of the same theme does allow you to express downward change nicely. The gong-like sounds at the end are also quite nice. Nice song :D (but if you are like I was, it would help to experiment with using other instruments ;)
