Script

Sure! Here's a simple implementation of a Snake game using JavaScript, enclosed in script tags, within a single HTML file. It can be played on a smartphone and uses pictograms for visuals.

To play the game, you can save this code in a `.html` file and open it in a web browser, or you can copy and paste the code into an online HTML editor. Upon running the game, you will control the snake using the arrow keys on your smartphone. The objective is to eat the red food dots without colliding with the snake's own body or the boundaries of the canvas.
