I can't even count the amount of angry tweets I've seen from people playing this game. It became quite the phenomenon! People would not quit until they made it past their current level. I actually never got into this game because I was afraid I'd become obsessed! How about you, did you fall into the Candy Crush trap last year? Are you still there? It's time to ask for help!
