Please make changes

I started off loving the game! The missions to earn money and gems was great but now there are no missions. I guess bc I got to a certain level Im not sure but I miss the missions. I have completed every collection except for 2. I cant complete them because the border collie cost 149 gems come on thats freaking ridiculous. And I cant complete the other collection bc I dont have the border collie to get the frog and use the frog to breed the
Bill frog... also around 139 gems to add another breeder seriously. The game depends to much on gems and there is no way to earn gems. Some in app purchases are fine but this is suppose to be a free game to enjoy. You cant enjoy it if you cant purchase pets bc you cant buy gems bc they are way to expensive and you cant earn them for free. Also some things cost to many coins I mean to upgrade close to 70,000 thats ridiculous. Please make these changes... if not Im gonna delete this game.
