1 star. I never rate games. It's really bad if I do. , severe lagging, glitching, being denied rewards and upgrades, after watching the shady ads, ETC....! I did reach out TO THE DEVS via email. Awhile ago and no response still. I will uninstall now after about a year of playing this. lag and glitching denies rewards and upgrades and kills game play so often that i no longer enjoy playing. The devs apologize yet they don't correct or fix any of these issues. False apologies by devs.
