There have been levels with more impressive and crazier effects, but no level will ever match the intensity of ABEL. For something that repeats its main effect so often, it does so in a way that never gets old and combines with the song to make you feel like you're being shot like a bullet through multiple universes at once.

The opening cube and ball set up the level extremely well, combining a otherwordly artstyle with Dienid's effects getting more gradual and gradual until that animated transition.

Then boom.

You're thrusted into a breakneck speed wave that explodes with color and only stops when the music itself screeches to a halt- only for you to be sent right back in to an ever crazier effect wave that continues until the level ends. ABEL's kaleidoscopic effects fizzle out as soon as they start- a psychedelic supernova of a level.
