Sure! Here's an example of a simple game implemented as a single HTML file, using JavaScript and enclosed in script tags. The game is interactive and assumes smartphone operation. It features a red stickman character represented by pictograms.
To play the game, you can copy the above code into an HTML file and open it in a web browser that supports JavaScript. It will display a canvas with a stickman character represented by a red pictogram. You can then interact with the stickman by touching the canvas on a smartphone.
