Sure! Here's an example of a Dragon Ball Fusion game implemented as a single HTML file using JavaScript:
Please note that this is just a basic example to get you started. You'll need to implement the character selection and fusion logic, as well as handle user interactions such as clicking on the canvas or buttons to select characters and perform fusions. Additionally, you'll need to properly include the images of the characters and fusions by placing them in the same directory as the HTML file.
Feel free to enhance the game as per your requirements and design preferences. Good luck with your Dragon Ball Fusion game!
