Sure! Here's an example of a simple shooting game implemented as a single HTML file using JavaScript and pictograms. Please note that this is just a basic example to give you an idea, and you can make any modifications or enhancements as per your requirements.
In this game, you can drag/click on the screen to move the projectile (represented by a red circle) and try to hit the target (represented by a bullseye icon). Whenever the projectile intersects with the target, the score increases, and the target changes color randomly.
