Features:

- When lost, the ball resets to the centre, and starts moving in a random direction every time (either left or right angles can happen) at an approximately similar speed no matter what direction.

- Paddles cannot go past the top and bottom walls, and never move sideways, rotate, or get stuck.

- Clearly legible scores shown for both players, and scores are correctly calculated as play progresses.

- Game play proceeds to end of match (first to 10 points), then displays winning message that identifies winner, and gameplay ceases (ball doesn’t re-centre and paddles stop moving).

- Upon gameplay ceasing (as above), a “play again?” message is shown, when clicked, game restarts with scores, paddles, and ball reset
