Game used to be good but after all the updates it's so laggy and buggy. Can't change the graphics, can't change coin skins, can't play Global challenges... woulda been cool if they didn't update so much :/ 2 stars cause it kept my unlocked characters and hats that I worked hard for. Chests make obtaining coins and gems a bit easier but it doesn't negate the fact whatever gems and coins I had had vanished.
