Geometry Dash Hallucinate is a massive collaboration between Subwoofer and 14 other creators. Every part of the design in this level is of high quality, from the lighting and colors to the background and art. It all comes together to create an intense level.
The level starts with a cube stage with many timing requirements. Immediately after, the player enters a half-speed wave segment with changes in size in between. At 32-37%, the beat stops, and the player enters a double-speed Nine Circles level in a tight space with many fake lines. The next sections are relatively easy to overcome.
One of the hardest parts of this level is moving from 60% to 66%. This section starts with two simple cube jumps followed by a ship section where the player needs to go up a tunnel made of fake blocks. The character then turns into a cube, kicks two spheres, and enters a UFO portal. At this point, the player needs to use the gravity portal to quickly move down the wave portal.
