Glitchy beyond all heck. Half the time, I don't get rewards for completing the level. The ad feature is hit or miss for rewards, such as crates, to spin the wheel, etc. Sometimes it won't let me watch the ad even if it says click here to watch an ad for the reward or bonus. I had to uninstall and reinstall as it stated there was an update even though Google play didn't have an update button on the page. At times, the bottom menu disappears and I have to exit out of the game to click on any of it
