Okay, been playin this game over 1yr. U did stop stealing my hearts. Now after level 1,000. 30 sec ads back, 2-3 ads for 1 play, impossible to win with 3 stars, game freezes when played more than 30-45mins. Its time to look for another game!!! 08/04/21 I've been play Jungle Marble Blast for mayb 2 yrs. I spend money, the optional challenges gives additional & multiple boosters. I completed Parrot Rescue & others 2-3 times, NO boosters. The game just freezes.
