Sure! Here's an example of a simple space shooter game implemented as a single HTML file using JavaScript. It utilizes pictograms for the game elements and is designed for smartphone operation.

To use this code, save it as a `.html` file and make sure to have `emozi_all/player.png` and `emozi_all/enemy.png` sprite images in the same directory as the HTML file. This simple space shooter game allows you to control a spaceship using the mouse (or touch on a smartphone). The spaceship can shoot bullets to destroy enemy spaceships. The goal is to survive as long as possible by avoiding enemy spaceships and shooting them down.
