that level is goated
i love the music too
it's just so deceptive too
my brother used to make levels that were designed to look like the robtop levels but were much harder
he did one called "The Unseen" that looked like clutterfunk but that level might actually have been a demon
Then he had one called "orbicular temple" that was made to look like theory of everything but it was harder
he would make levels that he called "Ring levels" and would have difficulty ratings for them, so the unseen was 10
but he made one called Ring Demon and that was probably an extreme demon
he had robot and ball sections in that that were barely even possible
and then he was making a Ring Demon 2 that opened with a small little wave patch that was darn near frame perfect
but he lost access to all of them
