''What is it'' 100% (Demon) by Booglee [3 Coins] | Geometry Dash

"What is it" is a level that if you didn't know any better, you would think it's a megacollab between a whole bunch of talented creators, every couple of seconds the whole level changes, from the decoration, the block design, the colors, the style, the effects, even the song, which is a mix in in of itself. Even though the level switches design so rapidly, being done by a single person, it stays consistent the whole way through, especially in terms of the transitions, being really smooth from one section to the next. There's a ton of variation in this level, some parts may be better than others, but as a whole package it's a great level with a bunch of detail put into it.
