I like the usage of particles and especially the warped designs but I find it to be kind of inconsistent. Some of the parts like the spider part don't focus on that too well and makes it feel more plain and uninteresting. I also wish it had some interesting pulses going on to give the colors a bit of spice, maybe some different shades of blue and purple because I find the monochromatic palette to be a little boring the more I play it. If the shaders were less strong and had some pulses to go with them I think they would've looked much more appealing.

I do like the last part a lot, issues mentioned aside. I really like when levels repeat their gameplay with a different tweak (in this case being upside down) when the song repeats itself.
