Sure! Here's a simple version of the Snake game implemented as a single HTML file using JavaScript and enclosed within script tags. The game can be played on a smartphone and uses pictograms for the snake and food elements.
You can replace 'emozi_all/snake.png' and 'emozi_chicken.png' with the actual URLs of the pictograms you want to use for the snake and food elements.
To play the game, simply open the HTML file on a smartphone or any web browser that supports JavaScript and interact with the game using the arrow keys. Have fun!
