Bubble Shooter Fun - Match 3

This is one of those very fun and addicting apps you hit the App Store to find. However, there are some problems that make this game very frustrating. Sometimes the balls won't stop moving the tiniest bit so you can't continue for what seems like an eternity. Sometimes the game freezes. Once it shot a couple of invisible balls that you couldn't see or get rid of without restarting the level or wasting a special power ball to blow it up. And lastly, for some reason it UNSAVED my level progress once and set me back two pages of levels.

Sometimes crashes when u finish a level. But addicting

I would rate this higher, and maybe even buy the ad-free version, if I knew for certain the pay version would work flawlessly. I've been stuck on Level 14 for weeks, getting the "try again" pop-up while the balls are still actively falling through the filter. So frustrating, especially since I can't find an explanation or instructions anywhere. Just seems to not follow the same logic as all the previous levels. I've given up!
