Sure! Here's an example of a simple Sniper Elite rifle shooting game implemented in a single HTML file using JavaScript and enclosed in script tags. In this game, you'll use pictograms to shoot down the targets.
To play the game, simply open the HTML file in a modern web browser, preferably on a smartphone, and tap/click on the moving targets to shoot them down. The goal is to accumulate as many points as possible by accurately shooting the targets. Each successful hit awards 50 points, while missing or allowing targets to go off-screen deducts 10 points. The game ends when you miss a target or hit the targets for a certain duration. The final score will be shown at the end.
