Bubble Fall is a bubble shooter in which the clock matters as much as your aim.
The goal. Pop the colored bubbles before time runs out. Join three or more of the same color and they go. The longer a round lasts, the faster the bubbles come down, so a slow start gets expensive.
The controls. Aim with the mouse and click to launch. Everything else is timing and angles.
The bomb. Now and then you get a bomb. Fire it like a bowling ball and it blasts the whole area where it lands, which is the quickest way out of a crowded corner.
A habit worth building. Bounce shots off the side walls instead of always shooting straight. Bubble Shooter Classic is a calmer take on the same idea.
