UPDATE This problem has become more frequent. I'm uninstalling. Changed my rating to one star. This is a fun game. A little easy, but it's okay just for relaxing. This is why I have it any stars at all. BACKGROUND MUSIC FROM THE ADS STARTS PLAYING RANDOMLY DURING THE GAME AND I HAVE TO CLOSE THE APP AND REOPEN IT FOR IT TO STOP. IT STARTS AGAIN AFTER A FEW MINUTES. I USE KASPERSKY SECURITY SO I DOUBT THE GAME IS INFECTED. PLEASE FIX THIS BUG.
