Eh, it’s pretty big by most conventional standards, but they could certainly be bigger!
yeah, definitely agree. maybe have upgrades that increase egg size, and egg number independently, preferably with one that increases eggs gained as well so you don't have to spend forever building them up. and remove the cap for how many eggs you can "hold" before filling her (if there is one) so you can watch it happen! Egg skins and options for belly texture/egg outline/bulges would also be fun!
