WARNING! Terrible battery hog by running hidden in the background processes (back button does not close app, just minimizes)! Spamming a single google ad (Yandex taxi) every minute. STAY AWAY! In reply to dev. Yes, you show a full screen ad after every game, but during any game (Yes, that IS stupid, and no, my phone is clean), I am constantly bombarded with an ad, that reopens in less then a minute. Useless and shady developer. Don't worry, will NEVER try another app from you again.
