As an AI language model, I can provide you with a simple example of how you could create a game using JavaScript in a single HTML file. Here's a sample code for a basic smartphone game with pictograms:
This code sets up a basic game canvas, draws a blue square representing the player, and allows the player to control its position using touch events on a smartphone. The game continuously loops using `requestAnimationFrame()` to update the canvas and provide smooth animation.
Please note that this is just a basic example, and you can expand upon this code to add more features, levels, scoring, and visual elements based on your specific game requirements.
