A Good Idea
You obviously had a great idea going into the making of this. It's a bit redundant after a while. It would go great as a backgroung loop on a video game menu or something. For some reason it makes me think of Metroid Prime. The ending is appropriate, which not many people do very well. Most of the time, endings are either too abrupt or too different from the rest of the song. This one, however, fits in very well. Good job.
