Sure! Here's an example of a simple "Dot Eat" game implemented as a single HTML file using JavaScript:
This game features a player represented as a red square and food represented as a green square. The objective of the game is for the player to move around using the arrow keys and eat the food by colliding with it. Once the player eats the food, a new food location is randomly generated on the canvas.
You can copy the above code into a new HTML file, save it, and open it in a web browser to play the game.
