Script

Sure! Here's a simple implementation of the Snake Game using HTML and JavaScript, enclosed in script tags:

You can copy the above code into a single HTML file and open it in a web browser, and you will be able to play the Snake Game on your smartphone. The game board is displayed as a 400x400px square, and you control the snake using the arrow keys. The snake grows longer when it eats the food (red dot), and the game ends if the snake hits the wall or itself.
