Sure, I can help you create a simple eating game using JavaScript and HTML. Here's an example implementation for you to get started:
In this game, you control a blue square using the arrow keys on your smartphone. The objective is to move the square around the canvas. The canvas represents the game world, and the blue square is the player.
You can also add more features such as enemies, collectibles, and scoring to make it a more complete game. Feel free to modify and expand on this basic example to create your desired game.
