Having found the time to play through the recent expansion, I was pleasantly surprised. The gameplay is still good, just... the adult aspect fell flat a bit to me. The scenes were okay. I'm still not sure if I like the new artists but time will tell.
On Sprites: I don't particularly like sprite based scenes and games, that being said, they were excellent. I do really wish they had just a bit extra. Even a single static CG per sprite scene would be amazing.
A personal opinion: considering the quality of everything else, it could be possible the Artist(s?) Responsible for the event scenes and animations could be dragging and not making much progress. Which leads to more of the Sprite and minigames type content since that's actually being made and worked on by (hopefully) passionate people.
