Sure! Here's a sample implementation of a shooter game using JavaScript and HTML that can be played on a smartphone. The game is designed to be simple and uses pictograms for visuals:

To play the game, simply copy the entire HTML code and save it in a `.html` file on your smartphone. Open the file with a web browser, and you should be able to play the shooter game using the arrow keys on your smartphone's keyboard. The player is represented by a rocket ship emoji (🚀), and the enemies are represented by bomb emoji (💣). Your objective is to avoid the bombs and survive as long as possible while collecting points. Good luck!
