So MC is just also a manipulative little bell end now. It was more fun when it was just Lily and her machinations. Kind of takes away from the taboo aspects when the characters turn on a time. Rachel has been pretty much assimilated and I suppose it's on to the mom now.
Things don't line up when there's like a single render per update but a complete personality 180 in the same time span. By the time the mom comes around there will still be a host of acts to explore with no barriers whatsoever, and it will feel unearned. The character design is top notch and the original personalities and motivations were on point.
Do a soft reboot while you still can, have Lily wake up from a dream or something and say "If only it were that easy" and start spending more time fleshing out the story and renders, while MC, Rachel and others offer at least a little resistance and inhibition. Not everything needs to follow the same formula, but a little more than a few in-game hours between "my older sister wont admit her feelings" and "I guess I dont really care if I got her pregnant" would be welcome.
