Ridiculous Amount of Gems Needed
There isnt a lot of substance to this game without paying money. So you can get along for a time without gems but its only a mediocre experience since you cant complete some of the more interesting functions.
Unlike Bakery Story where you can at least earn a gem for finishing a mastery, PetShop does not give you opportunities to earn them, but still requires you have a significant amount to complete simple animal purchases or crossbreeds. Even some missions cant be completed without them. It makes it boring.
*also mildly animal abusive. I mean seriously your animal is sick, pay gems/real money or abandon it? Thats not even right...
