Alien Blockade

Alien Blockade is an adapted version of the arcade game QIX. The player controls a marker and must use it to draw rectangles on the screen while avoiding the enemies. Initially the game area is black, but as the player creates rectangles on the screen a hidden image is revealed. If the player takes too long to draw the rectangles, the time will run out and a life will be lost. When enough percentage of the hidden image has been revealed, it's on to the next level.
