It's an avian invasion, and the only solution is complete vaporization!
HOW TO PLAY:
Click 2 birds to switch them, creating rows of 3 or more birds of the same color, which vaporizes them. When you see a flashing bird, or a wheel of 4 tiny birds, click them to clear all birds of the same color, or all birds surrounding them. Keep vaporizing until you score high enough to move on to the next level!
