Sure! Here's a simple game implementation in a single HTML file using JavaScript. The game involves a ball bouncing around, and every time it hits a pentagon shape, its speed doubles.

You can copy this HTML code into a file, save it with a `.html` extension, and open it in any web browser on your smartphone. The game will start automatically, and you can see a ball bouncing around the canvas. If the ball hits the pentagon, its speed will double.
