My simple advice for the dev:
Don't try to make the players sympathize with the MC. Don't try to redeem him. The game would be a lot better off that way. This new direction ain't it chief.
There was a discussion about this with another guy. I did consider whether a change in direction in the story would be received well. The reason for that is not redemption. I simply think there is more room to develop the story with this direction. I read your review, and I agree with many of your points. I admit I'm not a very experienced writer or game developer, and many problems in the game boil down to my inability to work cohesively across different areas of the game.
I'll address some of your criticisms and see if you can understand my perspective. They are by no means excuses. I'm not happy with the state of the game either, probably in different ways than you. There are lots of things that can be improved, but it's too late now. I just want to give the game a proper ending.
Corruption or mindbreak should be done slowly, breaking the characters' walls or will down bit by bit. Instead what we get here is everything it SHOULDN'T be. And there's talks of...romance?
I did say before that corruption is not a theme of this game, despite that may be what a lot of people are looking for when playing games similar to this one. But you can see that by, the MC straight up raping the girls he kidnapped, instead of waiting for them to be corrupted before fucking them. Mindbreak is also not a theme of this game. I explained it before when somebody else asked about it. I think that is a waste of character development. A broken character doesn't respond to anything much. It doesn't matter what the character was like before. The moment she becomes broken, she is the same as all the other broken characters. "Romance", has always been there, between the MC and his mother. And the MC has always been talking about his philosophies to his girl. I think the main problem here is trying to fit this game into the existing categories on F95 or other adult websites. The most accurate word I can think of to describe the main theme of this game is
obsession. The MC does not care how, but he will get what he wants. He isn't after torturing women or making them submissive.
Someone before you said this isn't realistic. But based on the real life cases I have seen, like Jaycee Dugard, this is actually quite realistic. The kidnapper didn't care what she thought. He just kept lecturing her on his philosophies. And after giving birth to a few of his children, he no longer tied her up. And she didn't try to escape. Her children didn't even hate the kidnapper. It's very different from what you see in games like Personal Assistant: Blackheart Edition.
And the pacing...well. The pacing is all over the place. Several timeskips this early in the game, I don't know if the game is intended to be a short one and is being rushed due to that, but everything feels like it's moving too quick to the point that it's really dampening my enjoyment of the game.
I agree. The pacing is one of the worst parts of this game. It probably would have been better if I focused on one girl alone, like the mother or Emma. What this game was intended to be was, well, entirely different from what it is today. Probably you weren't there in the early stages of the game, but it started off with the demon route only. Maybe that is what made you feel the change in tone in the MC. On the demon route, the original plan was for the MC to grow increasingly contemptuous towards humans, and to treat them no better than cattle.
The sex scenes, honestly, there's too many of them. That would be fine if they were longer and meaningful, but they are over very quickly to enjoy OR serve a story purpose, other than showing "look the MC is raping one of the women again"
The writing could really, really use improvement, specially in that aspect
That's also true. I tried to improve them with animations but the result still wasn't very good. I guess I am just not very good at making sex scenes.
The lack of a "hide" option on Android however has the textbox covering them up without being able to hide it to see them fully, and the heaps of dialogue during the sex scenes makes the textbox obstruct them often.
I don't know if there's anything I can do about that. The Android version is an automatic port from Renpy itself.
