Interesting story concept, and I really like that you never actually stated what it was the main character was going through. The music does a pretty good job of highlighting the process of, well... processing. I think there's some good feedback below about the drums, the only thing I would add is that a bit of variation in melody, chord progression or even just an octave switch on the guitar on some tracks might help to keep things interesting. Regardless, I enjoyed it overall. Nice job!
