honestly don't get the big deal. a bunch of people who can't code are upset with him for supposedly being a bad coder, and then an actual coder on YouTube looked at his code and said "It's mediocre basically". just looks like a bunch of kiwifarms trollings, that surprisingly a wide swathe of losers got hoodwinked into amplifying.
"Bad code" or not, if they actually spun their code into a game that works without too many/ too egregious bugs, what is the issue?
