KOSETSU

Template:Infobox Level KOSETSU is a 2.1/2.2 Extreme Demon mega-collaboration level hosted and published by ffwe, and verified by Taiago on 25 August 2024. It features a snow/ice theme that it has received praise for. The gameplay features frequent changes of game-modes and speed and seems to be partially inspired by Congregation and Slaughterhouse, and its music fits the winter theme. It also features drastic colour changes and various brief 'glitches'.

Gameplay

• 0-19%: KOSETSU begins with the player being required to precisely hit the orbs with complex timings. At the end, the player must hit the blue orb to land. Afterwards, a short animation occurs.
• 19-49%: The player has to do some complex timings, featuring cube, UFO, robot, and then spider, accompanied by significantly tight ship and wave sections. The screen begins to darken, creating an atmosphere of tension.
• 49-57%: The level reaches its climax, becoming especially challenging. The player has to face tight sections with straight-fly.
• 57-81%: The player enters a short and fairly challenging ball section, having to make a few precise cube clicks that lead up to the wave game-mode. After narrow wave passages, a ship section arrives, where the player must not click the two black orbs. Next comes robot mode, then one precise tiny-wave click and a challenging timing cube with orbs. The player must now click three times on orbs as a ball, later entering a challenging and spam-demanding spider section. Lastly in this section are two precise UFO clicks.
• 81-100%: The player is turned into a wave, having to traverse through narrow spaces, followed by a short ball timing section, UFO, a tight ship, and the final section featuring cube triple spike jumps. Finally, an ending sequence with the level's title appears.
