Sure! Here's an example of a simple army men role-playing game implemented in a single HTML file using JavaScript. The game can be played on a smartphone, and it uses pictograms for the visuals.
In this game, you control a soldier represented by the pictogram. By swiping left or right on the smartphone's screen, you can move the soldier accordingly. The soldier is confined within the game area represented by the `<div>` with the `id="game"`. The soldier's position is updated dynamically using JavaScript based on the touch events captured.
Note that you'll need to provide your own pictogram for the soldier by replacing the `src="emozi_all/pictogram.png"` attribute with the appropriate image file.
