I would be very great if you add female breasts but I hope it's won't be extremely big As car tires because when I search any game about NSFW mostly of them will be like that but do the Pokémons have Thier traditional gender?
I don't know what "their traditional gender" means, but you can choose the Pokemon's gender when you start a new game! You can also customize it with items you purchase in the shop.

Breasts are an interesting idea, you'd probably want to have new animations for grabbing and fondling their breasts, new clothing options like tube tops to show off their breasts and have rules for which pokemon like having their breasts fondled different ways! You'd probably want to also have the cosmetics be toggleable for people who like bigger breasts or no breasts
It sounds like a lot of work, but if you want to take it on yourself the game is open source. Good luck!
...you're gonna wait for a breasts update... So you comment the developer saying adding breasts would be great for you, then after they reply and tell you how much work that would be you ASSUME an update is coming? Wow... do you assume all game developers exist to create exactly what you what in their game?
