Geometry Dash Theory of SkriLLex is a Medium Demon level rated 10 stars, created and published by Noobas. It was first introduced in Update 1.9. The level was praised for its music synchronization (there is a remake called Theory of FirePower with a different song, design, and now-iconic wave part), but panned for its flawed gameplay. Despite this, Theory of SkriLLex remains tremendously popular and is now the game's most popular Medium Demon. A portion of this level appears in the level Ultimate Demon Mix, beginning with the triple-speed mini-cube and finishing with the mini-wave. If the user clicks too late at roughly 98%, the ball will hurl upwards towards unseen spikes, causing the game to collapse. Please pay close attention.
