Script

Sure! Here's an example of a game implemented as a single HTML file using JavaScript. This game involves moving a string of 10 balls connected to each other by drawing paths between them. The game can be played on a smartphone and uses pictograms to represent the balls.

To play the game, save the above code as an HTML file (e.g., "connected_balls_game.html"), and open it in a web browser on your smartphone. The game window will show a canvas with 10 red balls connected to each other. You can touch and drag any ball to move it around. The game will detect the touch and update the ball's position accordingly.
