This is part 2 of Homeworld Defender. This part adds: * Another character (Robot) which moves along a fixed path until it reaches the edge of the screen. * Collision detection - when Giga's ship hits the robot, the robot hides and a new one appears * Scorekeeping - When Giga hits a robot, the score goes up by one. The full game can be found here: http://scratch.mit.edu/projects/47819652/
