I would definitely say to look for some kind of alternative to Patreon rather than sanitizing anything that could make the game interesting. Patreon is just going to keep adding new, stricter rules that will inevitably hit everything. It's gotten so absurd that even pregnancy isn't allowed in games because it results in the existence of minors. That's just ridiculous.
You can still keep the current Patreon page up as a stopgap, since it tends to take them a while to actually notice and shut down any given game. Some relatively large games have been up for like 5 years without getting banned, including ones that don't even try to hide stuff like incest. But start getting an alternative ready, because I honestly wouldn't be surprised if the day comes soon that Patreon just bans porn altogether like so many other sites have.
