Geometry Dash Classic is an Insane Demon 1.9 level created by Versu5 (previously known as ComplexX). It is one of the first remakes of the Nine Circles series. This level stands out from other Nine Circles levels due to its prominent green color scheme and the lack of any ship or dual segments.
The level begins with a moderately difficult cube section featuring numerous jump pads and fake lines. Starting at 17%, players will encounter a wave segment. This wave segment is divided into two parts - a single wave and a dual wave. In the single wave part, players will face numerous spikes, fake lines, saw blades, and gravity portals. After clearing the single wave, players proceed to the dual wave section. This part of the level features a drastic change in gameplay. There are no gravity portals in this section. The obstacles players must overcome are limited to spikes and fake lines. The level ends with the signature elements of ComplexX. An invisible saw blade can cause a frustrating death at 97%.
