He's been told this many times by many people for over two years now. Keep that in mind when considering if he is "dumb" or "acting in good faith."
I do not think Braindrop is dumb (but I question the brains of some of his defenders) nor necessarily acting in good faith. Braindrop is doing just enough to keep interest and keep his donations coming in to live a new life.
There are a few things that can be going on here, or a combination of them (most likely).
He achieved success he never realized, so now is living a different life.
He has no idea where to go with the story, or got in over his head with the scope.
He got burned out making WVM, so works on it a little here and there but missing the former passion.
When he first started out, the game was solid (or it would have never drew us all in like it did). He released entire updates, full of renders and told the tale of the main characters. This was in the golden time of both him and the game. His focus was on the fans and the product.
After reaching a certain point, that is when he started running into "constant issues" (around the time he was nearing the end of chapter 1). That is also when he suddenly came contrarian, promised updates were often missed with excuses, and the focus of the story became more diffuse.
After Chapter 2 started, promised updates have become almost always delayed by a month or several. What he says he has done and what we all get are definitely not as grand. Mackenzie appeared, the only other person who has as much happen to herself as Braindrop does to his life. The game focus is no longer there, what he is making is not working for everyone, and suddenly the former quality is no where near where it was. Black boxes, duck faces, and now the new normal has become naked women running around, bigger T and A, and redone characters. The more you talk about these things negatively, the more they become part of WVM.
He is obligated to make up excuses and keep people interested, but he also gathers sympathy for everything that allegedly happens to him. He is afraid the money will dry up, that is why he is so active on Patreon with his constant progress claims and excuse engine! Now his focus is on the income and giving people just enough to where they stand by him while he does whatever and excuses his way out of everything.
It went from initially him making a game with maximum effort, to him doing the bare minimum to keep the money coming and allow his army of WVM simps to defend his every missed promise. Then, he demonizes and blocks anyone who questions him or complains. He filters Patreon, and has his defenders come in here to attack us (or they do it on their own).
