4 stars: Great game. Could you please find another way to promote in app purchases? I paid to get rid of the ads and it's annoying to still have ads interrupting game play. At least it's not in the middle of each level but a pop up before each level is annoying. Maybe just a little icon at the top, in the pause menu, before or after a game session.
3 stars: Rating would be higher,if the game didn't freeze up every time there was a pop up in the game. Pop so many balls and get a reward, great! But as soon as you exit that screen, the game is frozen and needs to be shut down and reopened to work. Same for chest rewards. The constant freezing caused me to quickly loose interest. By level 46, I'd already had to rest the game a dozen times.
2 stars: Too many game mechanics. Every 50 levels or so they're adding new game mechanics. Makes sense, keep the game fresh or whatever. However, the bats are the worst mechanic they could've used. Made me uninstall this game after just a few levels. The bats fly around and relocate if dropped and not popped, even when you drop all of the last bubbles, surprise! If you haven't popped the bats, the game's not over.
