TL;DR: Very well directed. Very very well animated. Good cartoon. I like.
The writing and dialogue is often bland as a rice cake, but there's so many fun compositions and styles playing around that are impossible to detract. A lot of them clash with each other (e.g. the sudden change from "arid desert" to "vaporwave land" was strange), but I don't think that goes against what this cartoon's bottom line is supposed to be, which is that the Rule-of-Cool reigns supreme.
All the designs are very appealing and easy to read, there's almost never any wasted space in the compositions, the soundtrack rocks, the hybrid of animation styles mesh very well, the hand drawn effect animations are gorgeous, the pallet swap during the vaporwave scene works great, ben-day dot textures adding a little extra visual flair to the 3d models, the chromatic aberration intensifying certain shots and actions to feel more 'unhinged' is super clever, there's too much cool stuff to pick apart!!!
All of the visuals are stellar and BURSTING with creativity, but give the writing a little more love and this would be a near masterpiece. Job well done!
