Arctic Lights

Arctic Lights is a 2.1 unrated collaboration created by EndLevel and Viruz. It is an extremely difficult remake of Nine Circles. The first preview was released on April 2, 2018. The level was verified (speedhacked) by EndLevel on May 28, 2018 after 12,000 attempts. Viruz created the first half, and EndLevel created the second half. Since EndLevel admitted to hacking the level after an exposal by ToshDeluxe, Metalface221 took the job and legitimately verified the level on 16th of February, 2019 after 35,393 attempts.

Gameplay

 * 0-14%: The level starts out with a cube section that involves very tight spikes and numerous hard jump orb timings.
 * 14-20%: After the cube is a memory ball segment with lots of fake orbs and invisible blocks, as well as tight orb timings like the first cube.
 * 20-25%: After the ball is a tight slow ship sequence with straight fly, and then a cube in transition to the wave.
 * 25-81%: This is the main part of the level and the drop of the song. It has frequent speed and portal changes, some invisible. Some parts have insane jitter-clicking, and the wave in all requires insane consistency.
 * 81-89%: At the end of the wave is an extremely short timing cube section and then a ship sequence that requires 1-block slow straight fly.
 * 89-100%: At the end of the level is a timing mini-cube section with jump orbs that have to be hit right at the correct time. At the very end is an easy ship sequence, and then the level ends.

Trivia

 * The level is the sequel to Hyper Paracosm by Viruz and TheRealSneaky. The two levels look fairly similar, as they’re made both made by Viruz (Endlevel made part of Arctic Lights, and part of Hyper Paracosm was made by Sneaky.) However, Hyper Paracosm is purple, and Arctic Lights is blue.
 * EndLevel says that this level is the hardest demon he has ever beaten. This is really significant, considering that he has beaten demons like Bausha Vortex and Erebus in the past. He hacked Arctic Lights though.
 * This was originally harder, but EndLevel nerfed it down to Death Corridor Finale difficulty.
 * Metalface221 officially verified the level legitimately on February 16th, 2019.
 * A semi-unknown Russian player named Sinon may have beaten the level legitimately with clicks and a microphone, although it's not clear whether this is legit or not.
 * EndLevel has recently announced a sequel to this level called Azure Flare, which is also a collab with ViruZ.
 * There is a v2 called Beat Aspect
