Changes in the pong.kv file

1. Design Changes: a. I have changed the colors of the paddle, ball, text, etc at different place as follows: i. rgba: utils.rgba('050E5C') ii. To use this I had to import utils from kivy.utils
2. Adding button: a. I have added a couple of buttons like ‘Start Game’ and ‘Play Again’.
3. Adding TextInput Fields: a. I have added a couple of TextInput boxes for getting the player names.
4. Hiding and disabling the unwanted components: a. Once I no longer require the components, I am disabling them by setting the opacity to be 0 and disabling them.

Further improvisations made by me

1. Changed the color of the gradle and the ball
2. Ask the user to enter the name of the players before starting
3. Display the name of the players besides their score
4. Give a logical end to the game as follows: a. Player scoring 11 first wins the game if the difference when the player scores 11 is 2 or more. b. Otherwise after scoring 10, the player will have to earn two more points than his opponent if both have reached 10 points by then. c. This rule is similar to that of table tennis.
5. Play Again feature.
