Geometry Dash Theory of Insomnia is a fan-made level in Geometry Dash, the popular rhythm-based platformer game. Many gamers regard this level as one of the most challenging Hard Demon to defeat.
The Theory Series was developed by Dorami, and this level is the second one. His challenge-level series and the confirmation of various Extreme Demons, including EnvY, Cromulent, The Yandere, Violently X, Idols, and Under Lavaland, are well known.
An auto cube segment with the abbreviation "GLHF" (Good luck and have fun) opens the level. With a simple half-speed ball that requires discrete timing and false thorns, spikes, and rings, the song and level begin.
The player then enters a mini-wave part with little gaps that can be easily avoided because of the half-speed.
The player then enters a simple cube part with gears and clumps of useful and worthless rings which are a little problematic.
Except for a hit on a yellow ring, the cube is now automatic.
Once the plunge begins, the speed doubles. Starting off is a simple UFO with spikes placed in oblique rows.
How To Play
As a square-shaped icon advances automatically through a number of levels filled with numerous barriers, spikes, and other dangers, you can control it. To progress through these stages, the player must jump, fly, and interact with objects while timing their actions to the beat of the background music.
