I can kind of see why ppl would turn away at the father's reveal. I think that the earlier that the tone of a story is set and revealed, the better. The second that guy appeared, I stopped caring about the lore, plotholes and almost everything, since the author decided to go for absurdity in the story's direction. That's the kind of element that makes all internal logic pretty much irrelevant.
And there's nothing wrong with that. Maybe it's just not your kind of story.
For me, I have a lot more issues with the dialog. In fact, I had to take a break from the game, because I got to a point where I wasn't really reading anything anymore, mostly because of how the dialog was being written.
I think the dev can write pretty well, all things considered. Especially descriptions and a narrador. But the dialog is killing me. Currently on chapter 20-something, so about halfway of all the available content.
Anyhow, if what you disliked about the game and made you want to drop it was the dad reveal that's fine, but it is what it is and expecting the game to be something that it isn't won't do anyone any favors. It might be that this game just isn't your cup of tea.
