Remix the game and add functionality to create a pong game using the following steps. 1. Make the paddle move right and left when the right and left arrow keys are pressed. (Start it at a fixed place on the stage, try x: 0 y: -160) 2. Make the start from a random place at the top of the stage (try x between -100 and 100, y: 150) and point in a random direction (try 135 to 155) and move forward (it should be going down). 3. Make the ball bounce when it hits the top or sides of the stage. 4. Make the ball bounce off the paddle by checking when it is touching the paddle and having it change the direction (try 180 - the current direction) and move away from the paddle. 5. Create a variable "score" that increases each time it bounces off the paddle. 6. Create a variable "lives" that decreases each time the ball goes off the bottom of the screen (check if y-position is less than -160). 7. At the start of the game initialize "score" to 0 and "lives" to 3 (or whatever value you choose). 8. Make the "Game Over!" screen show only if "lives" is 0, and stop the game.
