Very enjoyable, the liberal use of distortion and bitcrushing was certainly on brand for Doom 2016 and it's impressive that you managed to make something so damn dirty come out so clean.
There was a simple 3 note motif around 60-70 seconds in that I was looking forward to hearing again, I was certain that 3:05 would be the return but sadly no, not a major let down but I think it would have strengthened the piece a bit.
I haven't listened to many submissions yet but this is easily my favorite so far, well done!
