Vortex of Time

 is a 1.9/2.0/2.1 unrated Extreme Demon, notable for the fact that the gameplay was created by 98 people over 1.9 and 2.0. Koreaqwer was originally set to verify, but he gave up after a terrible fail at 91%. So instead, Minus and Kieas redesigned it to a 2.0-style level and gave it to Plusxexon, a semi-unknown Korean player, who states the level is around Carnage Mode difficulty. On 4 February 2018, he finally verified it, thus ending the level's journey.
