Catastrophic is a insanely hard Nine Circles level created by TheOne21. It has many tight wave spaces, inconsistent sections, precise, crucial timings, and numerous fakes. Due to this, it is generally considered an Insane Demon.
This is a Nine Circles level dedicated to the original 1.9 Nine Circles demons and their creators. The level follows the classic Nine Circles design and has a green colour scheme, also using the song Problematic, which was also used in another Nine Circles level, Problematic, which is significantly easier than Catastrophic. This level, in addition, is considered to hands-down be one of the hardest demons in Geometry Dash and is one of the hardest Nine Circles levels to date, the harder being Down Bass, Crimson Clutter, and Sonic Wave.
The level starts off with a very easy cube segment with very precise jumps and numerous spikes throughout. At the end of this cube segment, the player will quickly transition into a double speed ship sequence, with several gravity portals and some large spaces requiring decent flying skill. This is followed by an auto cube segment, leading the player into the infamous Nine Circles wave. This triple speed wave segment contains tight spaces, numerous size changes, and fake lines, with a few speed changes and very inconsistent gameplay throughout. At one point, the level shows text showing, "AYYY LMAO," as shown in the image above. Afterwards, the player enters a buggy ball segment which mostly revolves around very crucial timing. This segment is considered to be very annoying among the community, and numerous players fail here. The player then transitions to a double speed cube segment, resembling the end of the original Nine Circles, while flashing the names of the creators of the original 1.9 Nine Circles demons throughout. At the end, the level thanks Zobros, the original creator of Nine Circles, and NIGHTkilla, the person who composed the majority of songs for the original set of 1.9 Nine Circles demons. Finally, the level ends.
- You can skip the triple speed portal at a mini portal at 39%. This can be done with very crucial timing. If done successfully, this can cause a music bug and can also make the level significantly easier.
- As shown on Andromeda's video, you can also skip the triple speed portal at 43%, once you've entered the slow speed and size portal at 42%, if done correctly with a perfect timing, you are able to skip the colored sawblade, and skip the triple speed portal as well, it will also make the level much easier to pass through.
