I like Bubble Mania, and I'm glad I got to test it then get the real release! However, I don't like the idea of using gems, because how do you earn them? But anyway, I got down to my last 10 bubbles and a pop up scared me. It read: BUY 8 MORE BUBBLES FOR 6 GEMS. I almost tapped it because I enabled the SHOOT button. A gem trap already!
