I really use to love this game played it everyday because I'm obsessed with pandas. I bought the Panda pass with the guardians. I REGET IT!!! IT FROZE ON ME IM STUCK ON THE GUARDIANS SCREEN!!! I can't believe all those other upgrades I bought and all this time playing this game it never messed up until now! DO NOT BUY THE PANDA PASS!! PLEASE FIX!!! I miss my pandas and need to save the babies!!!
