DuoTasking is a multitasking-puzzle-platformer where you control robot and laser cannon simultaneously. When you move your robot from left to right, your laser cannon will move from top to bottom. Guide the robot across the screen to collect bonus items, and destroy enemies with the laser cannon. Pretty hard game as the game progress. Game contains 12 levels and 3 different difficulty levels.
