Sure! Here's an example of a simple game where you play as a ninja trying to kill all the enemy ninjas and collect chests. The game will be implemented as a single HTML file and will use JavaScript for the game logic. Pictograms will be used to represent the game elements.
To play the game, open the HTML file in any web browser that supports JavaScript. You will see a canvas where you control a black square which represents the ninja. The red squares represent the enemy ninjas, and the yellow squares represent the chests. Use the arrow keys to move the ninja around and collect all the chests while avoiding the enemies. If you touch an enemy ninja, you lose and the game will restart. If you collect all the chests, you win and a congratulatory alert will be shown.
Note: This is a basic example. You can enhance the game further by adding more features, levels, animations, sounds, etc.
