I get what you mean, but I don't feel this specific forum is the right place to criticize their YT video. Wouldn't that be better served on their Discord server (if they have one) and/or tweeting at them via Twitter and/or making a comment on the YT video itself?
You come across as super-aggressive and a bit whiney.
Please do remember that criticism is an art rather than an exact science. Tact, grace, skill, and truthfulness. Everyone tries to do it and only a few actually succeed at it. Most just end up being entertaining (James Rolfe of AVGN) and others either fade into obscurity or sell out (boogie2988, Skylent, TheLazyPeon, HiveLeader, etc) to make sponsored advertorial videos (while simultaneously running a Patreon!) about crappy mobile games that everyone will forget ever existed in less than a week
You seem to like pixel art and such so how about focusing on rephrasing your words in a way that is constructive rather than destructive. It is a skill that takes time and practice. I'm sure you will improve over time.
