Okay, i lower my level of criticism here ...
Jumping between feedee-normal-feeder mindset might be what many ppl want.
Maybe i'm in the minority with ppl who want the personalities set in stone.
However:
If the "normal" personalities get their feedee/feeder versions then the current 4 feedees and 5 feeders should also get their "normal" version!
Actually some of the feeders are rly attractive, and i found myself wishing they where less perverted ie.: normal characters. Same for feedees.
Guess i slowly acquire a taste for personality changes (or sholudl i say mindf***).
Still thinking that it is a good idea to keep the good stuff as it is - just adding up to it.
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!
