I love incest, personally. This game did a pretty fantastic job with the kink, as well. I play non-incest games, and thoroughly enjoy the good ones. My biggest complaint is that Gary did a piss-poor job of removing it. I haven't seen the new update content yet, because it took so long to get this update out that I can't remember enough of the plot to just jump right into the new update.
That's where the trouble lies for me. Since Gary did a very slapshod job of excising the incest content, by only removing the lines that were tied to the variable, the whole game leading up to the new update is now full of logical inconsistencies and broken references (many many lines referencing the incest/family story were not tied to the variable and thus left in), and as a result, it's very painful to play through the whole game again.
If Gary had done a proper job of removing all the incest content and references, having to replay from the start would have actually been an advantage. The game obviously still loses much without the filial relationships that were originally there, but it would have been tolerable without all the confusing back and forth that exists now. There is a lot to love about this game, but by gutting only roughly half of the incest content, the overall writing quality seems so much lower that it's a slog to get through it now.
Gary should have either left the incest intact, and tried his luck with Patreon, while also opening a SS page to hedge his bet, or done a more thorough job removing the incest content, so that the game doesn't feel so sloppily written. Honestly, there's still so many references to the original incest content in the game, that Patreon could absolutely still ban it if they were so inclined. They've banned games for less, and even ban based on actual fan-made patches existing without the dev's consent.
tldr: The bottom line is that Gary made the worst of 3 possible choices. He could have left incest intact, or removed it thoroughly enough that it would seem it was never meant to be there. Instead, he chose to half-ass it, and left the game in a shoddy state that upset the most people possible.
