Sure! Here's an example of a simple game in a single HTML file that incorporates JavaScript. Since you mentioned using pictograms and assuming smartphone operation, I'll use basic ASCII characters to represent the game elements.
This game simulates a battle between a revengeful samurai and a Mongolian enemy. It displays the actions taken by each character in the browser console. The game continues until either the samurai or Mongolian's health reaches 0.
Please note that this is a very basic implementation and lacks visual components or interactions. You can enhance the game further by adding graphical elements using HTML and CSS, as well as incorporating user interactions using JavaScript event listeners.
