As other reviewers have said, this game has been freezing for several weeks now and is almost completely unplayable - better for a couple of days and then started freezing again. I had been up to rewards for 40 days play in a row and lost all of it because of the freezing and now have to start over. I did email the developer, and they responded that they were working on a fix, but that was weeks ago. If it isn't fixed soon, they're going to completely lose me and a lot of others.
