The problem is that I have zero interest in doing awful things to other NPCs or even player characters, but I like it when it is the other way around. I like to upgrade the character to make them strong, then find some sort of disgusting or humiliating baddie and... well, sit back, purposefully not resist, and simply enjoy watching my own character get absolutely destroyed.
And the thing with that is the slower and more unnatural, exotic, or hardcore the peril - the better. So while things Lona can do to others sound interesting from the gameplay perspective, sadly I am only ever interested in all the bad-ends and debuffs she herself can encounter...
I've looked around the wiki, stuff like slavery, body mutilation, race, or even getting sterilized sound fun, so does pregnancy and STDs. So you are right that this game has a ton of potential, even if it doesn't go too deep into non sex-themed bad-ends.
