Can't control himself or maybe he doesn't want to? During game development, all developers face a problem - ideas are too ambitious, not enough time to implement all , investors are pressing at the dev team, publisher is also pressing, demanding results and in the end, as almost always happens, many concepts, locations, parts of the story go to the bin or will be postponed for DLC. Here he is not limited by anything except the mood of his investors from Patreon, so while his number of patrons are stable, he will not change anything in the length of the game, realizing even the strangest and sometimes inappropriate flows of his imagination. We have what we have.
He will not change anything, having that income and stable opinion, and like one well-known billionare will play in his sandbox.
UPD. If I was him and see where it's going, I would simply remove unnecessary things, such as: 60 fps animations back to 30, non-lewd long animations would stay only if they are awesome, remove Madame Rose and Sally.
