This is a fun game but is filled with greed. Don't spend any money and you'll be fine but once you start spending money, they take and take and take and you won't make near the progress as you did before you started spending money. The developer says it's based out of "luck and chance" but this is false and I've experienced it many times over. If you have to reach out to support, expect to wait at least 2-4 weeks before they initiate a response.
