Butterfly Effect

Description
Butterfly Effect is a somewhat easy remake of Nine Circles, created by Linco. Its color theme is emerald green/turquoise and was made in 1.9. Precisely, Linco started to create the level at the time of The Realistic (late April), but he published it in the middle of the summer. Due to its unusual name, it got stars several months later. This level, like Figures, tests the basic ability with mini wave and the consistently fast rhythm of the music and the absence of annoying passages, make the level very exciting to play.

Gameplay
The level starts with a somewhat easy cube with few fakes and lots of flipping with blue rings. Then the level continue with a fairly easy ship because of wide spaces and the absence of gravity portals. An auto cube sign the imminence of the drop. The music drops and the funny Nine Circles wave starts. This path features some easy fake lines and few gravity portals. Then appears a mini wave with seemingly tight spaces and mashing but can be cleared easily like the normal wave. The wave returns big and become dual, with a confusing path with fake lines and tighter spaces. Then the wave, single, returns double for a while and become normal again. Here the level continues with the easiest part of the wave: a somewhat long corridor with scattered sawblades, that can be avoided with lots of memorisation. The wave goes in mini mode and the level continues in a similar way to the first mini, with precise but easy timing. Near the end the wave goes in a mixed dual mode (normal/mini) which is the hardest part of the level because of tighter spaces and asymmetric reversals of the waves. Suddenly the drop ends, the wave goes in single normal mode and the name of Linco appears.

Trivia

 * This is considered one of the easiest circles ever, even if it is beaten by far from other levels (Problematic, Ultra Paracosm, Infinite Circles). Its difficult can be compared to Fractured Circles.
 * This is the only level￼, alongside The Realistic, to feature "spearhead" gears instead of "Blast Processing" Ines.
 * This is the only level, alongside Crimson Clutter, to reverse the order of flashing lights (4-3-2-1).
 * This is one of the few levels to have a title that isn't inspired by the name of the song used￼ and/or without the word "circles" in. An other example is Quasar (Level).
 * This is the unique level that uses introflexed clusters of spikes to decore the slopes.
