About the discussion about mothers, what I have to say: the guys who make professional visual novels are very careful with certain things because the most important for them is to please the largest possible audience. Simple things like not creating a physical appearance for the protagonist already help in this sense, because you decrease the likelihood that players will find the protagonist's appearance not pleasant.
In my case, I make these games in an amateur way and my only concern is to try to be creative. In the case of Solvalley, for example, I hardly restrict the scenes and this has a polarized effect. There are people who love Solvalley and there are people who hate it, without having a middle ground.
When I started doing HS Tutor, I wanted to try to make something a little more enjoyable for a larger audience, so I did not (and will not) include any male characters, among other things. I also tried not to make an asshole protagonist or very aggressive girls who are constantly insulting others.
Even so, my style still deviates a lot from what most people expect, so it is inevitable that my games always have some things that bother many players. This is a "flaw" in my way of creating these stories, but it is something I decided not to try to "fix" because otherwise I will not be happy creating these games anymore.
