Lilith's Throne has been like this for a while, and anyone surprised it ended up this way hasn't been following the game since 2016. I'm sad the story hasn't been pushed very far, but I feel like Dominion is a pretty complete experience by itself. Expanded modding capability/engine improvements and so on are I think totally fine updates in this context. As long as you read the changelogs elsewhere and don't have to read two pages of apology before every update drops, the pace of development is tolerable for a game that's mostly dead.
Yes, the game should run on Windows 11
Characters who don't enjoy domination usually choose bottom positions when dominating you, even if you start the sex scene with the resisting stance, IIRC. The way you change that is to go into the global fetish settings and force "love" on for non-consent, and maybe set some of the submissive fetishes to "dislike". That should make them less soft. If that doesn't work I don't really know what you can do. Play Trap Quest instead, maybe.
