Concentrics is a not-so-typical mouse avoider game. Instead of controlling the player you also control the world around it! Move your mouse from left to right to move the player, move your mouse up and down to rotate the world around! Click and drag on the orange ball to move it to the exit. Moving the mouse left and right moves the ball in that direction, while moving up and down rotates the stage. On some levels there is a pivot (an orange circle in a crosshair) which can be moved by clicking the desired location.
