Sure! Here's an example of a simple particle simulation game implemented as a single HTML file using JavaScript and enclosed in script tags. It can be played on a smartphone and I have used pictograms to represent particles.
In this game, particles are represented by colorful circles that move around the canvas. The speed and direction of each particle are randomly chosen, and they continuously update and move across the screen. The game automatically starts when the HTML file is loaded, and the resulting animation can be played on a smartphone or any other device that supports HTML and JavaScript.
