At this point there is nothing you can say to defend his actions.
I'm a game developer myself, and already worked in some indie and original games, and even as a substitute in big projects like Zelda for nintendo
With the amount of money that this Mister is doing by month, if he uses 30% of his budget, he can literally, finish the game in just 3 months, working fom Monday to friday and taking 2 days off.
In this point is literally insane to defend him, even forced blindness.
He just wants to get as much as money he wants, it's impossible to take this long to change the Tech of the game, i even offered some of my services, even making a reasonoble price, just because i like the game, but he refused. (said that had suficient people)
maybe he has, what he doesen't have is desire to finish now, in any way he is losing a lot of patreons for this, and creating some fanboys that defend him no matter what, the game will be finished when they are 80 years old, and still wil defend him like mindless bots.
it's your choice to believe in me or not, and idon't care which you pick, for me its undeniable what's happening here.
