Shukketsu

Template:Infobox Level Shukketsu (出血) is a 2.1 Extreme Demon collaboration level hosted and published by MadisonYuko and verified by Baeru. It is greatly inspired by kowareta, with the gameplay consisting of fast-paced segments with many speed- and game-mode changes. Shukketsu takes a different approach to the kowareta-inspired formula by adding colourful art and effects to block designs, considered by some creators as the 'art-core' style. The style is generally considered not nearly as good as the original, removing all of the soul and atmosphere. The level is also somewhat meme-themed, with text displaying community memes, inside jokes and sayings placed into the block design. Many have called this a poor choice.

Shukketsu began as a kowareta-inspired layout created by Gablor (then Shuri), which Gablor cancelled and made public. MadisonYuko picked up the project and decorated the level. Shukketsu's first version was released on 24 January 2020 and set to be verified by Gablor. After getting the motivation from participating in Fragile, Yuko began to remake the level in early 2021, altering some of the gameplay and adding duke, Lexy and Zentraa to the project. The level was finished and showcased on 17 September 2021. The level was set to be verified by lamp86, but they dropped it, and it was given to Baeru, who proceeded to verify the level on 3 April 2021 after around 20,000 attempts.

Victors of Shukketsu, such as Kaza and Johnfree, describe the gameplay as challenging to learn but enjoyable afterwards.

An official sequel, Kaikatsu is under development.

Gameplay

The gameplay of Shukketsu was made by Gablor.

• 0-6% (duke): duke's part in Shukketsu consists of fast cube timings with many orbs to hit, including dash orbs to hold down on. Around 4%, the player becomes a mini-ship and must carefully fly between spikes with help from a yellow orb and a yellow gravity portal.
• 7-29% (MadisonYuko): MadisonYuko's first part in the level mainly consists of cube timings with some ball timings and ship sections with orbs scattered throughout. The player changes speed slightly and often goes through teleport portals occasionally. At 27%, the gameplay speeds up to triple-speed as the title screen of the level appears in a digital-themed font with a glitchy aesthetic.
• 30-44% (MadisonYuko): During this part, the gameplay is much faster than the previous part, mostly at triple- or quadruple-speed. The gameplay consists of fast timings with constant game-mode changes between cube, ship, ball and wave. Cube and ball timings are basic, while ship sections are short straight-flying segments, often with orbs. The tight wave sections at 29-30%, 33%, 40-41% and 43-44% are full of gravity portals and blue orbs. The final wave section from 43-44% slows the gameplay substantially as the player prepares to enter the following dual segment.
• 45-52% (MadisonYuko): Yuko's third part in the level begins with a short ship and mini-cube-dual, with a ship above the mini-cube. After the dual, a tight wave section begins at 47% and ends at 48%. There are some cube timings before another tight wave section at 51%.
• 53-61% (MadisonYuko): The gameplay continues from the previous part with a tight ship straight-fly through a Clubstep Monster made of the structure of the level. After some cube and ball timings, as well as a ship straight-fly, a UFO section begins at 57%, where the player has to make timings to go through a few gravity portals. At 58%, the player enters a tight mini-wave section, with some controlled spam through slanted structures. Yuko's part ends after a brief cube dual and some cube timings.
• 62-78% (Lexy): Lexy's part in the level is fast and consists of ship and cube timings leading into teleport portals. The ship sections are full of orbs to hit and short straight-fly segments. The ship section at 73% is full of black orbs that must be avoided. A ball section follows this ship part before some slow cube timings.
• 79-81% (MadisonYuko): This part by Yuko is brief, as it is only one tight wave section. This wave section has many gravity and size changes, along with it being deceptively tight.
• 82-92% (Zentraa): Zentraa's part is full of structures resembling the moving parts of a clock. The part begins with a ship section leading into a long mini-UFO section containing a lot of gravity portals and several orbs. At 87%, the player enters a brief ship straight-fly segment, followed by some cube and wave timings. At 92%, the player enters a brief spider section.
• 93-100% (MadisonYuko): The final part of the level begins with a straight-fly through a corridor filled with spikes before entering a wave section at 95%. At 97%, the player must straight-fly as a ship through a tight spike-lined corridor to complete the level. The end screen has the level's name on top of a bed of flowers with a purplish-blue sky in the background.
