/* 
 Title: "Lift Off"
 
 Description: A rocket launching from a platform on Earth to the outer orbit of space. 
 
 Interactivity: 
 1.Press any key to enable the voice command line: "Ready to launch!"
 2.Move mouse upwards to make the rocket and the environment move. (please ensure that the 
 cursor is within the canvas when moving the rocket)
 3.Click the mouse to see the yellow  stars flicker and grow in size.
