Rate I would give: Legendary
From my video: "This is definitely the most random choice in the entire top 10, considering that as of me making this video it has a grand total of 129 downloads and 8 likes and at first glance it looks like an absolute mess... BUT, I think it's a very nice looking mess. Feel free to not relate whatsoever, but I've always loved extremely noisy and chaotic visuals, which will become very apparent when you see the top 3. Anyway, I can respect levels that are well made from a theoretical standpoint, sure they are impressive, but honestly I will always find levels that do their own thing way more likeable. Besides, I don’t even think it's easy to build something like this and make it look as good as 953 does. Also whenever I watch a video of this level, I always get so hypnotized by the repetitive nature of it..."

more than a noisy genre-bending realisation of a quirky song by black midi, this level to me is the visceral reaction to the most debilitating event of my life - a projected visualisation of a transcendental moment that sourced what felt like my lifes essence and cloaking it in abstract obliquity, entertaining the concept of distance between the creator and the work. 953 necessitated creative and spiritual self-reinvention, and its a miracle that it exists in the form it does - it's the culmination of my development of self. This level is my opportunity to let you all connect with me emotionally, and if it reaches you, i hope it reveals itself to you the way it did to me.

edit: its not all that. but its still pretty great
