The game was always about these aged up versions of them though, the main changes are just that the originally far meaner scenarios involving Elyon were cut along with their CG which could've just been left in the gallery, maybe even worked into the game as Cedric dreaming that it was that easy to manipulate Elyon or Elyon daydreaming/dreaming about Cedric being more assertive/doing stuff to her. I mean she already masturbates to the thought of him doing stuff to her before he even touches her sexually for the first time anyway.
And now the younger sister of Cornelia who even originally got aged up before you could do anything to her anyway, had her two fairly basic scenes cut, in favor of her new body that honestly looks younger than her original aged up one anyway aside from the bigger boobs, piercings(personally not a fan), and ugly eye make up that makes it look like she got punched in the face. Main downside to the change I'd say is how messily they're trying to blend the old babysitter content with the new relatively the same age siblings that just don't get along content.
Would probably be best if they just dropped the babysitter angle at this point and had him look after her because she's somewhat sickly and can sometimes suddenly needs someone to look after her, making the reason she turns emo that she's resentful towards her sister since she feels abandoned, from her perspective her sister doesn't really want to spend time with her she just feels obligated, something Cornelia uses to taunt/tease her only slightly younger sister(their original dynamic but aged up), and that she always prefers hanging out with boys over spending time with her(Cornelia's guardian work, from her sister's perspective is just hanging out with boys). It could even lead into her no longer being emo eventually after finding out that her sister did care about her but just keeping the new look. Also Cedric could probably heal her of whatever long term illness she has in this scenario, as a way of getting Cornelia a happier outcome than just tricked and enslaved, that would still happen but she'd also be relieved to no longer have to worry over her sisters health(Basically a reversal of the original scenario where Cedric took years off the life of her little sister and ruined her chances at a regular life on earth, here he'd be helping her live a longer happier life).
