I actually quite like this game. Do you have any plans to release it on Steam?
I understand that games like this are harder to make than typical VN games, but I'm a bit bothered by the characters' facial expressions, and the sex animation, which should be a highlight, isn't good enough. Another thing is how quickly and unsmoothly the relationship-building with the characters progresses. In a typical VN, there would be events where players can interact and talk with the characters without any sexual involved. This makes players love and feel attached to the characters more, without it needing to be just about the sexual things.
But doing repetitive tasks like making coffee, collecting trash, and cleaning doesn't make me feel more connected to the characters as a player, and it's actually a bit boring. It feels like the player is the servant instead, even though there are many other ways to build relationships with maids. I don't want to discourage you. I really like the games you make and want to see them get better.
