Down Bass

Down Bass is a Nine Circles level created by Spectra. It is often regarded as one of the hardest Nine Circles levels in the game. This level was hacked by its creator due to its difficulty, but got its rating back thanks to RedUniverse beating the level live and getting RobTop to rerate it. Players normally consider this an insane demon.

Description
Down Bass is a Nine Circles level of very high difficulty, and has a lime colour scheme, as seen in the beginning of the level, where the text says "Lime Circles." The level used to use 2.0 effects to somewhat troll the player, but these effects have mostly been removed. However, the decor is still very 2.0-like, and the user coins are still in the level. The wave is made difficult in this level by very long consistency requirements and many tight spaces in almost every area in the level mixed with gravity portals to throw off the player.

Gameplay
The level starts off as a fairly simple cube with some tricks here and there, but nothing too hard. It then is followed by a fairly difficult ship with tight spaces and a lot of straight flying required. The level then goes into a very simple cube that only requires jumping on some very easy jump rings, before the player is introduced to the wave. The music quickly picks up intensity and the Nine Circles wave is introduced. This wave is very long and takes up a very large part of the level. The wave has a tendency to throw many gravity and size changers at the player just to throw them off, with an abundance of many hard to tell fake lines. The hardest parts of the wave are the areas with an abundance of sawblades and constant size changers, occurring twice in the level. At the end of the wave, if the player makes it through, they must pass a somewhat tricky cube and ball that both have many fake jump rings and gravity portals. If the player gets through this, they will turn into a cube and fall down. The player MUST remember at the end of the fall there is a green jump ring, and that failing to hit it will cause a very frustrating crash around 98% or 99%. If the player hits the jump ring, they turn into a UFO and the level ends.

Trivia

 * There appears to be an earlier version of the level that no one beat.
 * Down Bass is Spectra's only featured and rated demon, and it only got there because RedUniverse legitimately beat it.
