Sure! Here's an example of a simple game called "Lil Runner" implemented as a single HTML file using JavaScript. It features pictograms and is designed for smartphone operation. Simply copy and paste the code into a `.html` file and open it in a web browser:
In this game, the objective is to control a runner represented by a red square and avoid the blue obstacles falling from the top of the screen. The player can make the runner jump by pressing the spacebar or tapping the screen on a smartphone. The game gets progressively faster as time goes on.
Note that this is just a basic example to illustrate the concept of a game. You can enhance and customize the game further by adding scoring, levels, sound effects, different types of obstacles, and more.
