I loved how you use the sliders to show the voice's inflections; very creative! And the darkness section was super fun to play. I felt the rhythm was very clear in the mapping while I was playing.
Great mapping! Both difficulties feel completely on sync with the song, and no hit circle is forced artificially upon the player to give the map more stars.
Banger OP and the beatmap feels good to play! As other comments have said, the last part on the insane difficulty is hard to read, but I'm sure with how good the rest of the beatmap is, it won't be a problem for long. Hope it gets ranked someday!
