(New Hardest) ameliorate by maxis044, cordeaux & Onvil

This level has been probably my biggest grind in the game yet, I've played this level daily for several hours, but the consistency gain from doing that has been absolutely insane. I spent 4000 attempts on the first day learning the level, after that I started playing from zero. Only having 2.6k from zero may seem like not a lot, but in my latest sessions, when I would play for like 4 hours, I would spend only like 400 attempts because of the level's insane length.
When it comes to the level itself, I really dig both the deco and gameplay. The decoration has a lot of different limitations such as using no groups, only using two color channels etc., and for that, this level looks insane. There are many spots where there's some super clever usage of blocks, such as using mini coins' rotations for decoration in several parts. The gameplay was extremely extremely consistent, I honestly feel like I could rebeat this like right now. But getting to that point took a lot of time obviously.
Also ignore the song, I replaced the song with a different one that doesn't sync with the level at all. I sometimes do this when I get too tired of the original song when playing levels.
