What can you say about this level that hasn't already been said? This is the only level in Geometry Dash in which its difficulty feels earned. Even for some extreme demons I really really like, such as Falling Up, or Death, or what have you, these could be changed to be easier or harder and the point of the level would remain mostly the same. This is a level that justifies its difficulty- the creation of a space designed to keep you out, designed to tell you, "this world is not meant for you." and it succeeds on this front with flying colors. Such a slow, churning second half really sells this, followed by its ending, one of the best ever made. Every death past the halfway point feels absolutely horrible, and I wouldn't have it any other way. You can't get any better than this when it comes to extreme demon design.
