KOCMOC (pronounced cosmos)^{[Notes 1]} is a 2.1 Extreme Demon mega-collaboration level created and published by the members of Cherry Team, initially verified by Trick on 12 March 2023,^[1] then re-verified by Zoink as an updated version on 13 May 2023.^[2] The level is heavily inspired by the former Top 1 Demon Slaughterhouse, with most of the gameplay consisting of tight, spam-based wave segments. The level's gameplay was entirely built by spk (formerly SpikeGMD) and later decorated by Cherry Team.

Upon the level's release by Cherry Team after Trick's verification, it faced criticism from top players concerning bugs, optimisation and balance. In response, Vernam, the level's host, released an updated version addressing several bugs. Konsi's part was replaced due to poor optimisation, with kivvvi stepping in. Zoink later verified this revised version.^[2]

A remake based on the original unnerfed version, KOCMOC UNLEASHED, has been developed by Cherry Team and set to be verified by Arshadow. It is set to be the hardest level in the game, competing against many other upcoming levels.

Gameplay[]

The gameplay was entirely created by spk. The listed creators are the level's decorators.

0-6% (Synd): The pre-drop splits into two halves. Synd's half starts with a half-speed cube segment featuring strict timings, size portals and crucial orb clicks and jumps, similar to Slaughterhouse's beginning. Glitch effects add to the challenge.
6-13% (Vinty): In Vinty's half of the pre-drop, the player encounters tight timings, jumps and size portals. The segment concludes with six dash orbs and two challenging timings with varying icon sizes, followed by a brief transition displaying the level's name before the drop begins.
13-29% (Sauzzeth): The colour palette shifts to vibrant purple and pink, replacing Synd and Vinty's dark grey. The level ramps to quadruple speed, intensifying the challenge through the wave game mode. The player must navigate with tight manoeuvres, enter a mini portal and face a compact wave section. A frantic spam section follows, leading into a ship segment. Here, the player must ascend briefly, hit a black orb and then execute a straight-fly along the bottom. The ship segment ends in a tight straight-fly that gradually slows down.
29-44% (bli + Sauzzeth): The level accelerates back up to quadruple speed, turning the player into a wave again. Here, there is a rapid automatic transition, leading into extremely precise gameplay, marked by arrows to guide the player and make it slightly forgiving. Midway through, the player enlarges briefly and faces a few seconds of tight manoeuvres. This section ends in a short ball segment with precise orb timings and clicks. To conclude, the player must execute a rapid mini-wave spam.
44-59% (Xatz): The level briefly slows during a transition before speeding up. Next, a big-sized wave segment requires strict timings and a quick spam section. After this is a brief ship section featuring a lenient straight-fly that quickly transitions to an automatic segment. Following that, a tight wave part changes size multiple times. The section ends with a mini-UFO part featuring three orb timings.
59-74% (kivvvi): The final section features challenging wave segments with varied timings, gravity shifts and size changes. It includes extended periods of wave navigation interspersed with a highly demanding spam section at the end, arguably the toughest spam segment. After navigating this spam corridor, the level transitions back to half-speed, accompanied by a thematic shift to a broken, foggy ambience.
74-81% (Deadlox): Like the pre-drop, the concluding cube section is divided into two parts. It is longer than the pre-drop and presents equally demanding timings, narrow jumps and various changes in size throughout, especially present in Deadlox's half.
81-88% (Cauer + Sauzzeth): The timings remain tight in Cauer's and Sauzzeth's half. In the last moments, the player encounters intense timing challenges akin to the finale of Slaughterhouse, involving a sequence of rapid double-spikes.
88-100% (Hantein): Afterward, the player meets the end-screen, featuring each creator's name and the level title.
