I agree 98% and slightly disagree. I'll try my best to explain my thought in a way that makes sense. To me it looks like he is catering to the most cancerous part of his fanbase. the fan that just CONSUMES like a brain dead zombie and faps and moves on. Aka, the COOMSUMER. These people for a lack of a better word, and I hate using this word, are NPCs. It is self-sabotage and a waste to cater to them in the long run in my opinion. They are soulless husks that will just move on or fap to other things, not truly caring or putting any constructive feedback and comments into your work to want to see you get better. Granted that is mostly on him as it isn't our job, but nonetheless.
He takes 5 months + per game and that is with no delays. Usually it is longer. Imagine waiting a long time between each game, but for each to be anywhere from lacking to shit tier. I do get what you mean though at the same time. He focuses on quantity over quality and just releases game after game each being a 30min-1 hour long shallow husk.
I think the old NTRMAN broke early on. Probably after Adelaide Inn, or the first Mitsuko Mother's Lesson update, as the story and pacing in the final second update went to shit.
He seems to not take any criticism and feedback done in good faith. I think he might be just pumping out these low effort tier games till demand slowly wanes and he is done with this. Maximize low effort games till you sycophants are remaining to eat it up then slowly fade into obscurity and disappear.
Maybe I'm too pessimistic, but all his latest releases, coupled with the lack of acknowledging of errors, and not seeing improvement, only games getting worse and worse after each iteration makes one forced to come up with their own conclusions and this is mine. A shame truly. He really has the skill and potential to truly make something of himself in this category and carve his name in it forever.
sorry for the tldr.
