Sure! Here's an example of a simple game implemented as a single HTML file using JavaScript, enclosed in script tags:
This example creates a simple game where the player controls a melon by bouncing it off the edges of the canvas. The melon moves diagonally across the canvas, changing direction when it hits an edge. The game is rendered using the HTML canvas element and the melon is displayed using an image.
You can replace "emozi_all/melon.png" with the path to your own melon pictogram image. The game will start automatically when the page is loaded on a smartphone.
