Script

Sure! Here's an example of a simple billiards game implemented as a single HTML file using JavaScript and pictograms:

In this game, the player controls a paddle at the bottom of the screen using the left and right arrow keys (or on a smartphone, touch controls can be added using JavaScript touch events). The objective is to hit the ball, represented by a white pictogram, and prevent it from touching the bottom wall. If the ball touches the bottom wall, the game ends and a "Game Over" message is displayed. Note: This is a basic implementation and can be expanded upon to include features like scoring, multiple balls, obstacles, and improved gameplay mechanics.
