Pong!
Description: Pong is a classic two-dimensional sports game that simulates table tennis. The player controls an in-game paddle by moving it vertically across the screen, allowing them to hit a ball back and forth. The objective is to defeat the opponent by having the ball move past the opponent's paddle. Pong was one of the earliest commercially successful video games, and helped lay the groundwork for the video game industry.
