I don't know why or how you got this impression, but every kink in the game would be avoidable. But at the moment, I don't have any plans because I write as I go. I don't have everything planned out. I adapt my writing according to my crowd; I don't want to shock my fans; I want to please them and have fun writing this story.
Here's some friendly advice. If you're setting up a project and you want public support for the project, you have to tell folks what the project is. Not many devs do this, but a well organized presentation, along with clearly laid out production goals - and meeting those goals - will encourage folks to trust you.
Take the questions about lesbian, girl on girl action, for one example. There are games that focus on a female protagonist and they feature lesbians. People who like those kind of games see those labels and they play them and "support" them. There are games about ex military vigilantes saving damsels in distress and setting up a little harem of women that also work as spies for him - and people who are into that will play those and "support" them. There's all kinds of games and all kinds of tastes, but people generally do not like "everything."
It's like any product, you clearly label it so people know if it's something they are interested in. If you tell us all that you don't have a plan and that things will go with the flow, most of us are going to sit back and wait. I don't want to support a game that has stuff in it I don't like, and most people feel like that.
I'm not telling you what kind of game to make. In fact, I strongly suggest you don't design a game by committee. Write an outline, get the whole story in your mind and plan it out. Set it up in advance. Tell people clearly what you're making. Fans of that kind of entertainment will see you have a clear vision and they might be more likely to support that. But nobody wants to start helping out financially with a game only to find out a year into it that the story changed and there's a bunch of elements in the story they don't like. They'll feel like they've wasted their time and money.
Anyway, again, just friendly advice. Have a good one.
