The game has a core loop where you connect and pop bubbles of matching colors to progress. i find this mechanic keeps me playing for hours.
Play by aiming and shooting to pop bubbles, you connect and pop bubbles of matching colors.
No extra buttons or toggles are stated.
Save power-ups for difficult levels to optimize your chances of success. Aiming strategically to make the most of your shots is better then just shooting randomly.
