The level was rated on May 22, 2022. Many consider it the current hardest level in the game, although some players such as spaceuk disagree, believing that the level is easier than Slaughterhouse and Sakupen Circles.
Wasureta (忘れた) is a 2.1 Extreme Demon mega-collaboration hosted, verified, and originally published by Crazen, being later republished by Augi with the "verification" by DTDom. Augi's friend Vapor later reverified the level for a bugfix update on April 17, 2021.
Crazen was a skilled American player in Geometry Dash. He was known for beating several Extreme Demons such as Zaphkiel, Plasma Pulse III, and Digital Descent, as well as attempting to steal and verify Bloodlust and making good progress on his own Low Detail Mode copy without permission from Knobbelboy.
On August 19, 2020, he uploaded his first video, a completion of Wasureta. It was his first Extreme Demon, which most believed was an incredible achievement as only a few other players had beaten it as their first Extreme Demon.
