Rate I would give: Legendary
From my video: "...The amount of detail in desespoir is nothing to scoff at and I am extremely impressed by the fact that this was mostly made with the restrictions of the 1.9 editor. Remember how I said I like noisy visuals? Yeah well I might be starting to repeat myself here but there's just so much happening in every single frame of this level with the added bonus that all the details are actually coherent. You could rewatch a video of it 50 times in a row and you would still keep noticing new things that you didn't notice before. I also do enjoy the somewhat spooky vibes that the style is giving. The gameplay is surprisingly enjoyable too except for the difficulty spike that is the fast wave"
