My Free Zoo Mobile

I love this game. I played zoo tycoon on a PC when I was a kid and I could spend hours creating and planning. This is very similar but there is NO way to effectively play this game and keep leveling up in a timely manner without spending really money. There are hardly any ways to earn diamonds and when you do its only one or two at a time. The prices for certain animals or enclosures or decorations seem outrageous. 700,000 dollars for one animal? I would have to play for months and not do anything but collect from my shops to get that much. That’s not fun- I just want to play the game not have to buy diamonds with real cash just to afford a lion. I also wish the updates would bring new flowers or stores and stuff to decorate with. I am also having an issue with the app quitting on me randomly. Otherwise this game is well constructed and very soothing. Not zoo tycoon but it will do.
