Fatgeria: Feeding Russian girls into imobility (itch.)
You should add and even check out for yourself Fatgeria. It has gameplay that you can choose to turn on and off and the dev team is currently working on the next update. The dev even started a weight gain drive on DeviantArt and Twitter for this beautiful girl of royalty. You can find everything here along with update posts/chatting in the forum.
