I think, he mentioned the netorare content more for in general and not because you added something like this. Many devs out there start games, saying it won't have certain content or they are being vague about it and later (sometimes really far into development) add that content nonetheless. And often enough out of context or for "drama purpose". And the devs are suprised when the backlash happens, especially when they made a story that caters mainly to the harem crowd in the beginning. Nothing to be seen here, though.
As for the update, it felt a bit out of context for me. First we see a glimps of the the farm life and get background story. And then, with this update, without a real transition we move from the barn into kind of a coffee shop. A bit more context between the last barn scene and the first shop scene would've been good IMO. The differences between the human and demon route are minimal for the moment. Other than that, I like it and wait for more to come.
Those developers deserve the backlash they received. I totally understand that, but like you said, "Nothing to be seen here". I haven't broken any promises. I even specifically said the demon route contains supernatural elements. And I also did what people requested. Some said the supernatural elements were annoying, so I added a human route and removed the red eyes. People asked for the ability to name saves, and I did it. If they find the sword scenes to be out of place for the human route as well, I'll remove them and replace them with something else. If what people ask does not contradict with what I have in mind, which is now the demon route, and is within reason, I'll do it.
I think one thing that people don't understand, is the direction of the story, but honestly it's in the overview. It's not just about a guy that has nothing to do except kidnapping girls to breed and milk. That is not a story. The main story was always about his obsession with his mother and changing the world because of it, whether in the human or demon route. The difference is in how he would do it, and so the difference is minimal for now because we haven't even reached the main part of the story. I mean, you probably could imagine how he would do it in the demon route now.
Admittedly, I'm not very good at writing backstories. I find it quite boring, especially when I have to make renders for it, so I wanted to move to the core part of the story as soon as possible. But I understand what you mean, I too have thought whether I should give a bit explanation between the barn and the shop, but I thought it was self-explanatory enough. He captured many girls and sell their milk in different ways like with milk tea.
I really wanted to get to the introduction of his sisters in the next update, but I guess I got some things to fix first, seeing that a lot of people aren't happy with this update.
