One thing Icstor could do to maintain interest in his own game is to create more than one storyline for the same character.
Let's say the player has already reached the point of having sex with Sarah and Caroline (I don't know exactly how far each relationship goes in the last version). At this point, it is normal to lose interest in continuing to develop the plot because the climax has already been reached. However, what Icstor could do is create a new role for the characters. For example: Sarah is now committed to help Caroline rebuild her clothing store. Putting an established character in a new role is fun and gives motivation to developers who are only satisfied when they are creating new things.
I didn't play much Milfy City, but I'm pretty sure it's possible to have sex in different positions with Sarah and Caroline whenever the player wants to. This means that at least for these two characters, he already had enough material to create new roles and renew his interest.
About Patreon, people need to understand that it is not a crowdfunding site where they are funding a project. Patreon's philosophy is to give financial independence to artists. If an artist already earns enough to dedicate 100% of his time to his art, it makes no sense to give him more money. In fact, most likely that extra money will be detrimental to the guy's productivity.
So people need to take Patreon's goal seriously. If the guy says he needs 5k to work 100% of the time in the game, giving 50k will not make him work 1000% of the time ... From the moment the goal was reached, pirating the game is more beneficial for the future of the project than putting more money in the guy’s pocket.
