Thanks for your comment. I'm also prefer gentle giantess stories and there is too few game with that content focus, it's also a reason why I wanted to create this game in the first place. You don't have to wait that long, I plan to release the next update in just a few hours or next day at max.
Regarding the boobs size, I would have to redo all sprite and scene from scratch to make it happen, sorry I can't really do that. However, there will be four more characters that will be introduce later on and some of them will be smaller than Patty so you may like one of them for sure.
