I enjoyed it alot, but...
I don't want to say it sounded "unvaried" (honestly, its a DnB built atop the Song of Storms), because that just isn't fair. However, I feel the biggest gripe I had is you never really broke free with the drums.
It sounded as if you were about to break into some kind of frenzy over and over again with the drums, but they never got louder, they never really broke free.
I had to listen to this with some big headphones, so that may influence this next statement, but the drums seemed heavily defeated by the loudness of the rest of the song. I'll have to listen again with speakers sometime, but all I have are the cruddy laptop speakers to deal with at the moment. :|
Otherwise, this song was great. The melody had a a midi-ish sound to it, but in a good way. In a retro video game way. :)
3/5, 8/10.
