I liked this game.... Until it decided to FORCE me to use a booster and I can't get around it in any way at all. I can't play unless I select it to use it. I've exited the app and gone back and still, can't PLAY AT ALL unless I pick the booster. I'm not in tutorial mode, I shouldn't be FORCED to use anything I don't need. I'd rather use it when I'm not whipping thru a level w no issues and ACTUALLY NEED it. Now, I won't play at all and uninstalled. Wow, after reading reviews glad I stopped now
