Underwater Bubble Shooter - bubble buster game

Underwater Bubble Shooter is the fast and furiously fun bubble shooter that’s all about popping bubbles!
Gameplay is very simple, you just need to tap the screen with the finger when crosshair arrow is pointed on any bubble on the screen. There is no strict order which you need to follow when you popping bubbles. You need to figure out the easiest and the fastest way to pop and blast all the bubbles on the screen. Every level is possible to complete in multiple ways. Score is directly dependent on time that is left after completing the level. With better score you will gain more level stars and for every star you will gain 10 upgrade points that can be used to get more bullets, more time per level and to slow down rotation of the crosshair arrow.
Try to complete all 150 levels and become bubble blaze genius!
