Cool Twist On Bubble Shooter Game!

I really like this version of the bubble shooter game. The bubbles are dynamic, like real bubbles. When you hit them, they jiggle around, and if they jiggle enough they may stick to nearby bubbles. I just wish it didnt aim by tapping where you want the bubble to go; makes it too easy to hit your target, no visual judgement needed.
.
Also, it claims to have several bubble packs, and they are even credited in the about screen, but I cant find any option to change the bubble styles. Is that only available in the paid version? If so, why is it advertised in the Lite version? Thuis makes me wary of paying for it.
