Mostly looping
I mostly liked the background music. The background was mostly a loop, a pretty catchy one at that. However, the main track was a bit slower, too slow to match the background track. The music really relied on the background more than the parts which get altered. That's not really a good thing.
However, I did like the theme. I really got a feel for the style that the music was supposed to follow, which is good. Sometimes I like the half ambient/electronic noises that generate overtime. Those, are another positive factor in this movie.
Overall, I would say the music is great, however, you need the main track to be a bit, faster, and give it some variation. Instead of mostly the same noises, you could use a wider selection. Still, awesome music. I would enjoy it a lot if you managed to bring a larger variety. Nice try!
