KLAX is an action/puzzle game where you catch falling tiles and create rows, columns, or diagonals of a single color. The story revolves around your character's attempts to clean up a mysterious mess on Earth using their unique abilities.
The gameplay involves catching the colored tiles as they fall from the top of the screen, and then combining them into lines of the same color to clear them. As you progress through the levels, the falling tiles increase in speed, appear more frequently, and come in a variety of colors, making it increasingly challenging to create the required patterns.
