Sure! Here's an example of a simple bouncing spikeball game implemented in a single HTML file using JavaScript. Please note that this is just a basic implementation to give you an idea, and you can modify and enhance it as per your requirements.
To use this code, save it into a file with a `.html` extension (e.g., `game.html`), and put it in the same directory as your `emozi_himawari.png` image. The `emozi_cat.png` image should contain a pictogram of the spikeball.
When you open the HTML file in a browser, you will see a spikeball bouncing inside the game area. If the spikeball hits the left or right wall, it will change direction, and the bottom wall will increase its width by 20 pixels. You can further style the game area and customize the game logic as per your requirements.
Note: This code assumes you have an image named `emozi_apple.png` in the same directory as the HTML file.
