Don't worry, I totally understand where you're coming from & I'll be careful if I add any such changes. It won't be something that happens out of the blue or accidentally. The player will need to work towards it via feeder upgrades, etc., and it'll be presented as the girl discovering the desires she didn't know she had or being corrupted into feedism through the player's actions. So any changes would hopefully be believable.
I'd love to add many more personalities in the future and versions of the feedists without the feedism might happen!
