I love it when people who missed the point of my comment get angry at me for supposedly missing the point. You're thinking about blank slate characters and that's not what I was talking about here at all.
Also, I think you are mistaking player incarnate and viewer incarnate, which are two completely different things from different types of media that serve different purposes.
In any interactive media, the protagonist is, by definition, player incarnate, literally - you are in control of the character.
And it's great that the protagonist of this VN has a backstory and his own character.
BUT
He is not accepting player's inputs. They are not his. He does not believe in the choices the player makes. He is half-assing the actions that are supposed to be made by his own choice. It undercuts the player agenda and the whole point of interactivity.
Because when you decide to do something - you don't maybe kinda try to do it, you just do it. But the protagonist of this VN doesn't freaking care about completing anything he supposedly decided to complete, unless he is actively being electrocuted. So your choices barely matter. And it sucks! And I'm annoyed that more people aren't annoyed at this.
I'm so tired of people praising mediocre VNs just because they have good furry art.
