You get extra points from me for making it actually feel as fast as you set your bpm. Many songs only had me bobbing my head in half time, but I was head banging at 200 beats per minute to this! The ascending progression that stops after the fourth note feels unresolved and adds to your spookiness factor. It would have been nice to have some variation, but I do like the sequence that you do have. Overall great job and thank you for sharing!
