Ninja Head Suggestion: add option to disable certain content/fetishes. The two types I can see being a turnoff for some people are amputee and fart. Especially amputee content might be traumatizing/triggering for some.
These fetishes should always have a toggle option: gore, amputee, scat, watersports, fart, rape. Ofcourse if it's central to the game, and hard to omit, perhaps options to skip scenes or simply a warning before the scene. I understand that disabling rape or fart content would be near impossible without creating plot holes.
Also what's the plan for translation? A large part of the game is still poorly translated. I don't recommend using translation software.
Also if someone has trouble migrating an old save to a newer version, just rename the save "file1".
