The whole moving into one big mansion and slave/maid was a bit much for me. It was totally heading into a simpler direction I feel. I wish it just focused on the mom for a while and the aunts later.
Yeah, the game really set up that it would be about finally being with the mom and establishing a long-lasting, romantic relationship with her over time. And, as players, we only saw the "at last" moment (from the MC's perspective, albeit a huge shock to him). Then she backed away from it quite a bit, it felt like the game was going to be a lot more about developing an intimate relationship with her over the long haul, so a slow burn to get there.
I don't mind some of the other stuff that took place so far, because if there's no committed relationship with the mom yet, it should be expected that the MC would do other stuff in the mean time. But I really wanted the story to focus on the mom and develop that a lot more than it did.
