I don't know exactly why this creator decided to end this game but incest is not an excuse. Sooner or later creators realized that they can't continue to make games of this theme. As for patches they don't change the story or the dialogues, at the restaurant scene with Alison for example is like you talk to a girlfriend not your mom. If you don't care about story and dialogues and you skip until the sex scene and you like the girl to say "fuck me bro" instead of "fuck me baby" then ok but this is not an "incest theme game". You can do it with all the games by applying such a patch. Patches and forced changes make things worse. Just choose a theme that the site allow and create the game as you like.Madek couldn't even handle a consistent production cycle with one game on his plate. Working on two games simultaneously would be a disaster.
I'd really like to see Two Weeks continued also, but clearly he hates the game and wants to move on. He killed Alison and probably wants people to stop asking for Two Weeks to continue. Incest isn't the issue here either. It's just another excuse. That could be worked around with a patch or something. I mean, these Patreon rules / problems started before this game was even created.
I dunno, we'll see what he comes up with for his new project, and if it has the same appeal as this one did. I'd think just losing the incest would cause some of the potential interest to disappear. I mean, Two Weeks was really carried by that B+S relationship.
My opinion is the creator to make a new game with Jennifer as the main female character. Anyway good luck to the creator whatever he will decide to do.
