Regarding the use of the dialogue: I mean, sure but I put a good amount of effort into the dialogues making them as similar to the originals as possible...
Regarding the Puzzle, I find it pretty easy especially since there is only three options to chose from.
Personally I think that we should keep Taight as she is and make Ava the player spouse? Idk. I think her scenes are a bit more romantic than many so it could work.
