Sure, here's an example of a simple Pokemon Infinite Fusion game implemented as a single HTML file:
Pokemon Infinite Fusion
Select two Pokemon to fuse:
In this example, four Pokemon icons are displayed (Pikachu, Charmander, Squirtle, and Bulbasaur). When a user clicks on one of the icons, the corresponding Pokemon is selected. The player can select two Pokemon, and the fusion result is then displayed below.
Please note that this is a basic implementation meant to demonstrate the concept of Pokemon fusion in a single HTML file. You can expand upon this example to add more complex game mechanics, visuals, and additional features as per your requirements.
