The intro got my attention, but near the end of the segment from about 1:00 to about 2:00 I felt the song was becoming just a bit dry and repetitious. Fortunately, the song then had a lot of variation in the melody, and then later in the tempo and sound (I think that you changed the cutoff gate of a low pass filter?) to keep things interesting. By the end of the song, it had my attention again! I think that it came to kind of an abrupt stop, however. You might have been intentionally going for this, but to me, it felt like the song was building up to something that didn't really payoff. Some might disagree with me on this though, as it does punctuate the song and give it definite end. But I was hoping that there would one more really interesting segment to hear instead of just having the song stop.
Overall though, I really enjoyed this. This actually reminded me a bit of the Vectorman soundtrack, which is a VERY VERY good thing! I hope to hear more!
