Geometry Dash Sine Wavs is an Insane Demon level with 10 stars and 3 user coins created by TheRealDorami. The level is a recreation of Nine Circles, one of the game's most popular levels. Sine Wavs, on the other hand, employs a green color palette, giving the level a distinct look and feel.
Sine Wavs begins with a moderately challenging cube segment that includes phony lines, spike clusters, and traps. The ship sequence that follows is also fairly difficult, with uncomfortable flying and gravity portals that make navigation difficult.
Following the ship sequence, players will enter a simple cube segment that will lead to a triple-speed wave segment. This wave part is the level's highlight and where most players will struggle. The segment is tough to negotiate due to the numerous phony lines, sawblades, traps, and impasses. The wave segment also contains numerous gravity and speed portals that players must use in order to continue.
The dual section in the center of the wave segment is easier, but it still contains multiple traps that players must avoid. Following the wave segment, players are given a brief respite with an easy half-speed cube portion that includes a few tough jumps. After that, the level closes with an anti-gravity mini-wave part that leads to the creator's name and the written "GG."
