That's a high praise, Hollow Knight has such a beautiful soundtrack. You're correct about the challenges, It was 4am when I was filling out the information and I quite honestly couldn't tell if I did B or C. I think it's a better fit for A or B, than C since the notes are in reverse order, but sound different when played back, because of the reverb and note ends. It's hard to tell from the images and the wave form, but at 40s, all the notes go in reverse, but because I didn't change or match the endings of the notes, the reverse side sounds slightly different and has different timing.
