Flamewall
Template:Infobox LevelFlamewall is an upcoming 2.1/2.2 Extreme Demon mega-collaboration, hosted by Narwall, Valentine, Skub, Surjaco, and RicoLP before he left the project. The project has set multiple records: as the longest finished Top 1 level, at 6 minutes and 46 seconds long; and the largest mega-collaboration in the game's history, with 54 parts consisting of 407,143 objects and over 100 playtesters and decorators participating. The level was previously set to be verified by OneAlphaHelix, who dropped the level citing difficulties posed by physics changes in Update 2.2[1]; verification was passed on to the player Cuatrocientos. Flamewall is intended to be the hardest level in the game[2], competing against numerous other upcoming levels.
Gameplay
Flamewall has been highly praised for its consistent design and fun gameplay compared to most top levels. It is considered a "flow" level as it switches between game-modes very rapidly throughout. The base gameplay is not very difficult, which is unique for a Top 1 - the main difficulty is in the level's length and requirement of nerve control. OneAlphaHelix has stated that most of the gameplay is roughly Main List difficulty, although certainly easier than any Top 10 with the exception of Codependence (which has since dropped out of the Top 10).
The color scheme of Flamewall is generally orange (following the fire theme) with a few sections changing to primarily white and gray to match the song's intensity. The decoration is notable for maintaining a 1.9 style, but has been criticized for not having much depth in certain sections. This is likely a result of object limitations (as it was completed in 2.1), but questions about a potential 2.2 redecoration have been asked by numerous people. As of now, there is no mention of this taking place especially as the level becomes close to becoming verified.
Flamewall is also known for having a ridiculous amount of clicks for one level - OneAlphaHelix has stated that the level requires over 1,250 clicks in one run. It is more click-intensive in certain parts, but the overall number remains roughly balanced over its duration.
Verification
Flamewall is currently being verified by Cuatrocientos, a skilled Spanish player whose hardest level previous to the verification was LIMBO. Cuatrocientos took over the verification after OneAlphaHelix, the original verifier (who also uploaded the level's showcase) lost motivation after the 2.2 physics change and dropped the level on January 19, 2024. OneAlphaHelix's record before he quit was 62% (by 2.2 percentages; this was equivalent to 60% in 2.1). Cuatrocientos has made rapid progress on the level after picking it up, achieving a run of 24-80% on February 2, 2024 in his twelfth stream.
