Geometry Dash Windy Circles is an Insane Demon level rated 10 stars created by keiAs and is known for its difficulty, as it is a remake of Nine Circles. The level is noted for changing colors on a regular basis and is themed in a Nine Circles style.
Windy Circles begins with an unseen jump, which is a jump that the player cannot see until they get close enough to it. The cube phase that follows is challenging, requiring the player to employ strategy to overcome the different timings and gimmicks. The player is then taken to a micro-ship segment that demands they fly in tight places and pass through a gravity hole. Timing and trickery are also required in the following ball section. After that, the player enters a moderately tight ship segment with a gravity gateway. The level then drops, forcing the player to time a blue leap orb to prevent crashing. The Nine Circles triple-speed wave segment follows.
Windy Circles' wave portions are white with a flashing background that cycles through the colors. The wave portions also have numerous distinct backdrops. Due to the challenging memory chunks and small spaces, the level is deemed hard, though probably a mid Demon level.
