For what this is, it's much better than most of your submissions.
I know you generally tend to invest in the comedy significantly more than you do in the actual animation, but I still feel like increasing the frame count would both make it funnier, and provide something enjoyable for people who don't find the comedy all that funny:
The joke of the animation being stiff isn't contrasted by anything in the movie itself, making it loose the appeal it might otherwise have: there's a reason why stiff animation is funny in cartoons like the Spooky Month series; there's parts where the author will animate things smoothly so it makes the stiff animation more jarring and therefore funny.
This is true of almost everything you've made: the "joke" of the animation being stiff and limited isn't really all that funny if there's nothing to contrast it with.
It's like trying to bake a cake using only sugar and flour: it might taste alright, but it's not really a cake; just as when you make an animation with only keyframes and voice acting, it might be kinda funny, but it's not really an animation.
If I'm honest though, I generally found myself enjoying this much more than your previous works, but that's probably because this one isn't just hopping on a current trend and trying to get views and attention: it comes across as more of a genuine parody of something you enjoy, rather than "oh shit, new thing came out, gotta make a cartoon while this is still relevant" like Hunkin' and some of your other stuff does.
Lastly, I don't think you should be posting people's reviews of your stuff on Twitter: that REALLY encourages the people who don't like you to keep disliking you, and it feels like you're trying to shame people into only leaving reviews that you like.
"Everything By Everyone" goes both ways: you can make whatever you want and the YouTube audience who've migrated over here because of your stuff can come over to get it past judgement sure, but consequently there's no "right" or "wrong" way to respond to reviews and people have and will continue to make fun of how sensitive you come across if you're trying to put stuff on blast or elude to certain kinds of criticism being "wrong".
