Sigh. Oh, well...
It seems to me, that this series have been your main subject material for this year. Let me start off, by saying: You have talent, no doubt about it. However I highly disagree the usage of this talent for these series, where I am going to review this series for a next few paragrahps.
The animation and graphical quality is there,no problem there. However the main issue is a massive barrage of thought problems:
As I understand, this is supposed to be a self-conscious "show", where the characters have a comprehension of the shows situation. There is no problem with the basic idea, but you have executed it so.... not-well, that it falls under it's own weight.
The gist is the "Humour paradox", that you are trying to achieve, (The less funny it is, paradoxicly it is funny how unfunny it is) added with the self self-conscious effect of breaking the 4th wall and parodying itself.
However the attempt to make effect above is so obvious, that it is breaking the core mind of this idea (in my personal viewpoint). It loses it's credibility with constant repetition, failed storytelling/pacing (dragging things too long (With a exception of this episode)), and cheap insults with a lot of swear words. Speaking of which...
Using foul language as humour is most effective when used unexpected, and in un-reasonable situations. However tossing words left and right feels like beating a dead horse, with a fancy walking stick. It might be funny for some people, but... meh... But I think the biggest problem is the fact, that this work is in a loophole of self-parody, which breaks the main intention itself.
I consider this episode the peak of this series, because this episode is attempting quick-paced hit-and-miss humour(in my opinion:better). (Therefore this might be the best episode in comparison)
Here is a healthy advice: abandon this project, (ok, maybe just finish it with a episode or two) start something new, experiment with new ideas. Because I can tell: Making good video-game jokes, isn't really your cup of tea.
I consider WGJ4K a waste your talent, I know you can do better than that, and you will.
I hope you start your rehabilitation from this project, and achieve greatness, that you deserve.
Best of wishes.
