Well it's kind of like making a movie here....That's maybe my biggest complaint about the game. Much of the repeatable content from earlier versions lacks any acknowledgement that by v.013 you're now eight or nine months into vigorous sexual relationships with your mom and sister.
He is still in the Principal Photography phase!
Once he has the game and story fleshed out and near completion, He can then go back and set the variables needed to make the story make more sense and replace any context and continuity issues in the script that in Movies is done via reshoots after the editing process has started.
Then he can have events set dialogue flags and have the dialogue system check the flags to give you the proper response for the situation and relationship the characters are in.
Very difficult to do that on the fly since he may not really know where the story is going yet. And to try and do it now just means his time would be spent on correcting dialogue that could be better spent making more content for us to see.
That is a problem with just about all the Patreon pay as the dev goes offerings....
If he spends a lot of time correcting past scenes then the complaint is there isn't enough new content added to warrant the monthly patreonage.
