Geometry Dash Black Blizzard is an Extreme Demon level rated 10 stars, created, verified, and published by KrmaL and Krazyman50. The level has a gloomy design and effects that frequently impede the player's view. The orbs near the drop are completely black. It blinds the player to the function of each orb, forcing them to memorize it.
The level begins with a half-speed mini-cube portion with minimal dark decorations and multiple challenging timings.
The player is about to enter a difficult, normal-sized cube portion. This section, like the preceding one, contains a lot of buggy orb timings. It is embellished with a lot of fog and lines flowing across the screen. Throughout the segment, two moving crosshairs jump from orb to orb. The majority of the orbs that the crosshairs jump to contain little saws that will kill the player if they are hit too late. At the end of the portion, there are two sets of triple spikes. The screen then goes black while the level name appears, marking the descent.
The drop begins with a triple-speed UFO segment that includes many gravity shifts and some spam. It then moves on to the ball, which has numerous extreme timings.
The following level portion is regarded as the most difficult in the entire level. It contains incredibly challenging mixed dual segments, most notably the mini-wave/UFO mixed dual at the start, which necessitates near-perfect handling.
The final segment runs at half speed and challenges the player to travel as both the ship and the wave, in both sizes and gravity, through tight and claustrophobic sections with an occasional darkening screen. It continues for roughly 20 seconds before the level ends.
