Sure! Here's an example of a game called "Hungry Frog" implemented as a single HTML file using JavaScript:
Hungry Frog Game
This game is displayed on a canvas and allows you to control a frog using the arrow keys on your smartphone or keyboard. The goal is to catch as much food as possible by colliding with it. Each time the frog catches the food, it will respawn in a random position. The game loop continuously updates the canvas, checks for collisions, and redraws the frog and food elements.
Note: Pictograms are not used in this example, but you can modify the game's appearance by leveraging pictogram libraries or by drawing custom pictograms on the canvas instead of basic shapes.
