Sure! Here's an example of a simple game about rockets and meteorites implemented as a single HTML file using JavaScript and pictograms:
This example creates a simple game where the player controls a rocket using the left and right arrow keys on a smartphone. The goal is to avoid colliding with the falling meteorites and try to score as many points as possible by allowing meteorites to pass through the rocket. The game ends when a collision occurs. The score is displayed on the screen, and the player can restart the game after it ends. The rocket and meteorite pictograms need to be replaced with actual image file paths for the game to work properly.
