Geometry Dash LIMBO is an Extreme Demon level rated 10 stars that is hosted and published by MindCap, co-hosted by Djoxy, and validated by BGram. A blend of indigo, dark blue, and crimson are used in the level's design, which is reminiscent of the final quarter of weoweoteo's Extreme Demon Marathon but more intricate. Additionally, Hinds and Vlacc's roles in the Cybernetic Crescent have a theme with one another. Without the use of visual distraction and with the implementation of original gameplay elements, it is designed to be the hardest memory demo. According to MindCap, the level's January 2022 iteration would have likely finished in the Top 20–30 of the Demonlist. The version that was later enhanced according to several playtesters was of Top 1 difficulty. LIMBO's level entirely depends on the player's memory skills, so assessing the game's difficulty will be challenging.
On August 27, 2022, BGram went back to the level and began playing on an even more improved version that, in his opinion, might be harder than Slaughterhouse, the old Top 1 Demon on the Demonlist. BGram ultimately certified this version.
