This game is very fun, but I am experiencing a weird bug where the game will prompt me to sign into my Google Account everytime I tap the screen when I'm in the menu. If this gets fixed I'd rate the game 5 stars. EDIT: My account recently got altered and have lost all of my progress. Please fix this issue. And to those of you who are currently playing the game... DO NOT SIGN IN WITH YOU EMAIL. Your progress may be reset as well.
