Editing Flamewall (section)

===Verification===
The verification of Flamewall was initially given to OneAlphaHelix, who achieved 60% (62% using 2.2 percentages) on the level. However, partially due to the physics changes in Update 2.2, he lost motivation and dropped the level on 19 January 2024.<ref>https://discord.com/channels/1057610354865221653/1057613272339189853/1198015126100512859</ref> Following this, Cuatrocientos took over the verification of Flamewall.<ref>http://youtube.com/post/UgkxmTq4WHrU_KO4Uzvu-iO0uZUijUiUYpsk?si=t6Xzped2bXZ9XeFx</ref> At the time, Cuatrocientos's hardest completed level (according to modern placements) was Solar Flare,<ref>https://www.youtube.com/watch?v=_BKXvJZiGVY</ref> which was then ranked #20 on the Demonlist, which made verifying the level a significant jump for him. Despite this, Cuatrocientos made rapid progress on the level, unexpectedly achieving a fluked run of 3-86% on 10 September 2024 and later a run of 24-100% on 19 August 2025. On 31 August 2025, he experienced a devastating fail at 99% on the level,<ref>https://www.youtube.com/watch?v=1gZEJI-2yQQ</ref> which is generally considered one of the worst fails in Geometry Dash history, even drawing attention from song artist Camellia;<ref>https://x.com/cametek/status/1962206612019654796</ref> this feat was also achieved practically right after he failed at 50%. He would fail at 99% again a week later on 6 September 2025.<ref>https://www.youtube.com/watch?v=5OQkJD4KWTM</ref>

On 21 September 2025, after what was essentially a 73% fail in the previous attempt, Cuatrocientos finally verified Flamewall after 221,703 attempts, two deaths at 99%, and 220 streams.<ref name=":0" /> The level was then uploaded on Narwall's account and rated Epic soon after on the 24th. After initially being placed at #3 on the Demonlist on 24 October 2025, it was later swapped with Amethyst on 19 December, making it the second-hardest-rated level in the game, behind Thinking Space II.
