Great difficulty man! Nice tech mapping. Only thing that stands out to me that I didn't really point in the timeline is that you seem to change some patterns with no or only very minor changes in the music for variety. I'd avoid drastic changes like that because it just makes it feel weird like you're playing different maps, not the song . Good luck!
Thank you for the mod and the compliment! c:
About the patterning, I did it carefully, keeping consistency in mind, and I think it bring a lot of variety while playing instead of having the same pattern everytime. I tried to keep the core concept here; but made them still vary a bit to keep it fresh while playing.
