Sure! Here's a simple implementation of Atari Pong with a spikeball using HTML, CSS, and JavaScript as a single HTML file:
This HTML file creates a canvas element to render the game and uses JavaScript to handle the game logic such as moving the paddles, bouncing the spikeball, and detecting collisions. The game starts automatically when the page loads, and you can control the left and right paddles by swiping up and down on the screen on a smartphone. The spikeball and paddles are represented with simple colored rectangles.
