Sure, I can help you create a simple game where NPCs (non-player characters) become smart. Here's a basic implementation in a single HTML file using JavaScript:
In this game, you will control a player represented by a green rectangle on a canvas using touch events on a smartphone. The NPC, represented by a red rectangle, will move randomly on the canvas. The game loop continuously updates the game state and redraws the rectangles on the canvas.
Feel free to enhance and customize this game further to fit your requirements!
