Keep firing on those squares and rectangles until you get to the star! Use your mouse to move and fire your weapon but make sure you don’t touch any of the boxes or the game will be over. You can advance through each difficulty setting by shooting all the boxes down until they become stars that you can collect. This game definitely presents a challenge and it will take some time to master. It is a one player game but you can play against friends by taking turns and trying to outscore each other.
