It's a fun little time waster, much like Cookie Clicker, but a really interesting Idea i had, was at the beginning, you should give the player a choice between harvesting cum, or breastmilk, and then the game flops to either Boobs or testicles. as a guy, I can only take so much talk of cum and testicles. Or, once you finish Cum mode, then Breast milk mode is unlocked as a harder version. Bigger vats, smaller sell prices, and higher Stem Cell exponent cost.
