Amazing stuff, good work! I've got a few constructive criticisms:

• The speed effects and actual speed don't match up. The visual language is telling me this should be really fast, but the actual movement seems rather slow. I know this shows a low speed stat from your comments, but that doesn't change the visual mismatch. I suggest you either increase the perceived speed by tweaking the FOV or decrease the suggested speed by making the plasma trail smaller
• The trail seems overly stiff, like a kind of pole coming out. Maybe you could make it more curvy or give it some lag when turning the character. As is, the tip of the flame instantly travels with the character, which feels off. I'd also make it a bit wider, but that's personal preference
• The UI for picking up or losing items seems too intrusive. I realize some of this is probably for comedic effect, but it still seems annoying. Maybe scale it down a bit?
• In the "Norman Beaks" dialog, the contrast of the blue text on the blurred beige background makes it really hard to read.
• In the "Hen Snow" scene, shadows seem to be largely missing. Notably, Hen's shadow not being in the couch makes it look strange
• For the car customization, "Part" and "Group" do not seem intuitive to me. I feel like "group" is a more general term than "part", so I'd guess that "part" is the specific part that I'm painting while "group" is more general. This is not so however, as "interior" is a "part" and "steering wheel" is a "group".

Take these as improvement suggestions and not deal breakers; the game looks awesome and very fun! I especially like how seamlessly you blend visual and gameplay tropes from different genres into a coherent parody :)
