Geometry Dash Top 100 Hardest Demons

TOP 100 HARDEST DEMONS-UNOFFICIAL
By Gamerichie

INTRODUCTION
I wanted to make a list of the hardest demons, but with something unique to all the other lists out there. So, in the end, because I wanted to keep debating at a minimum, and also because I'm a slight overachiever, I didn't settle for Top 5, Top 10, Top 20, Top 30, or even Top 40. I finally decided to go with Top 100 Hardest Demons.

RULES1. Only  (must have at least ) levels accepted!
2. I will try to take all of your opinions into account when editing this list, and if I do not agree with you I may wait until other people comment or debate your point.
3. Also, don't be rude or mad at me or anyone else for their opinion in hard demons. There is no exact way to measure how hard a demon is, thus no one is really 100% incorrect. However, that does not mean someone who says Stereo Madness is harder than Cataclysm is correct!
4. An asterisk (*) denotes a level with a secret way (this applies for everything in this thread). For levels with a secret way, they are ranked based on the difficulty of the level excluding the secret way.

Enough with the intro. Here's the list:
