While the theming and progression are top notch, I find this level to be overcomplicated by the way its gameplay works. The concept of multi-activation on orbs is ineffectively applied for this level. The usage of the concept is rather to make the level more difficult. This level could have been fine and even better if it is just XL demon level with simpler yet still engaging gameplay without any extra twist. Of course, not saying that all multi-active orbs should be all gone, some of them have purposes to be there without having to copy+paste orb and making it looks messy, like the pink orb at the beginning.

For decoration complaint, I find 54% wave to lacks of background effect to be as great as the previous Black-White wave, but nothing else to complain fruther. Overall, this level is great, I like 61-75% parts (excluding the base gameplay) to be especially, more level should use full songs like this. I want to also mention putting the big credit text at 84% rather than at the end is very smart.
