Like others have said way too many ads. So I turned wifi off while playing. It made things better but you can no longer watch ads for boosts, which makes things a little more of a grind. Controls aren't the best. And then today my game froze. I shut it down, then restarted and got a pop up forcing me to accept an agreement to collect personal info if I wanted to continue. Uninstalled right away. It's too bad too, I was enjoying what I had played up to that point.
