Jungle Legend

Bubbles rather than swapped gems are what you're matching here: you aim and fire colored ones from the bottom of the screen, and landing a shot next to two or more of the same color clears the whole cluster at once. The stack of bubbles creeps downward the longer a round runs, and letting it reach the hut waiting below ends things and sends you back to the start. Bubbles with special effects are worth prioritizing since they clear more of the board per shot than a plain match does. It's a shooter at heart, quicker on the trigger than most puzzle games filed under the same category.
