I have some more recommendations, maybe to add further playability to the game you could add a system where the more previously dated women that are obese but not immobile around town, thing start changing. like the food options being served being extra fattening and the new women around town are chubby/fat/very fat as a baseline, or new activities catering to fat people showing up around town.
Also, maybe add other towns with unique events that you can travel to by train or canal, maybe if you fatten up your own town enough the surrounding ones start getting affected by rising obesity too.
Plus, if enough towns get too obese, the government might start trying to curtail the trend in some ways which could add some late game difficulty. If the player gets past this obstacle maybe make it so that the people in the towns are very fat/severely fat/nearly immobile in size.
Maybe add higher weight stages past enormous for the people you date in the care facilities, just add the ability to fatten them up into room filling blobs with like 2-4 more weight stages.
Also, player character weight gain could be a cool option. Being around people who eat so much food has got to impact ones own waistline. maybe have some roll reversal with your date slimming down while you get increasingly obese.
I would also recommend updating the check out descriptions, they are all the same for the different body types at almost every weight. I don't know if this is a bug or not.
I also have some bugs to report:
1. if a characters height is 5', 0" tall, it gets shown as 4', 12" tall
2. if you select for maximum cellulite but no stretch marks, the descriptions don't tell of any cellulite during the game
