For now Abigail will be running the farm store where you buy animals. That is why her hair is more messy than Stardew Valley.
The facial expressions for the store I think are okay for now. They are supposed to be kind of comical for running the shop.
For now she is the main focus girl so I will be making more pictures of her. I will work on other pictures for her weight gain phases.
How the weight gain will work?
In Stardew Fatties as the hearts of the girl increases so does the weight of the girl. They can get pretty big before marriage. I will do something similar to that.
What will the difference be?
The bigger weight gain increases will be after marriage. So after you marry Abigail she will start putting on a lot more weight. Just like in real life after you marry someone they don't care about weight as much.
What does this mean?
She will gain weight before marriage but she will do all she can to keep it hidden from you. We will see how well that works! After marriage she will let herself go and wear more revealing clothes around the house only. In public she will still be covered up as much as possible.
