Is this game getting any better?
Meh. It's been stale for a number of updates. I've been unable to replay it from version 15's old saves and hold any interest. IMO, too much new clutter is being added and not enough being done with the loose ends already in the game. All the hotel girls should have sex scenes by now and actually long before now. Unfortunately even after 6 years, one still does not.
Sorry you're not enjoying it. I'm not sure why your saves aren't working. Regarding the content, the story is continuing down the same path and I still plan to add optional side stuff to do like gardening, if that counts as clutter. And as for Autumn, it would make me a worse creator to rush anything out before it's ready. Because Autumn starts as a religious prude, she is harder to get any form of sex from.
