Imma tell you a "secret"---he has always wanted the prologue to be longer, but couldn't do so in the original. Also, I don't know why you, or anyone else, complains we don't have family content yet. We can't fuck them yet anyway like 99% of incest games. Most of the beginning content with the family is just talking and bathing (with just Jaz and Jaiden) anyway lol
1. How is the current prologue better than the previous one? I wasn't a huge reader, but another user made the point that the character writing in the new one is actually really poor in comparison? The graphics look about the same, the touching groping system is the only thing that's new (and even that isn't shown that well).
2. The reason why not having family content is bad is - because that's what the dev is trying to sell with his remake. He is trying to claim that the rework was necessary and that the product will be improved due to this decision, BUT if he shows no family content then it's similar to a company trying to sell a car, and only taking a photo of a random tree for marketing (while claiming that "it's the fastest, coolest car in the world"). 1st releases are meant to tease the upcoming content so the fans could get hyped (and pledge money) - because it works.
3. Why couldn't the dev dedicate a couple of more updates to finish the previous game (give a few endings), and make the remake into "Twisted World 2"? He's already changing up the story & systems enough, hence what's the issue with that?
There's just too much wrong in terms of how this remake was done already, I think that wanting a "longer prologue" hasn't added anything to the game (and there're even arguments to say that the old one was superior in terms of the character writing). Groping and kissing systems are sure nice, but again the dev could've finished the previous game instead of throwing it away.
