Sure! Here's an example of a simple game implemented as a single HTML file using JavaScript and enclosed within script tags. The game is designed for smartphone operation and incorporates pictograms.
In this example, the game is a simple one where the player can move a character represented by a pictogram using arrow keys on their smartphone. The player pictogram is loaded from an image file (replace `'emozi_all/game.png'` with the actual path to your player image). The `handleKeyDown` function handles the player's movement based on the arrow keys pressed, and the `drawGame` function continuously redraws the canvas to display the player's current position. The game starts by calling the `startGame` function.
