Sure, here's a simple implementation of the classic Snake game using JavaScript and HTML. Save this code in a single HTML file and open it in your web browser. You can control the snake using the arrow keys on your keyboard. The snake initially moves slowly, and as it eats the food, it gradually speeds up.

In this game, you control a snake using the arrow keys on your keyboard. The snake moves around the game board to eat food represented by a red square. As the snake eats the food, its length increases, and the game speeds up. The aim is to make the snake as long as possible without running into the game board boundaries or itself.
