Sure, I can help you create a simple Pokemon game as a single HTML file using JavaScript. Here's an example code that you can use as a starting point:
In this example, when the page loads, it displays an image of Pikachu. Whenever the user clicks on the image, the score increases by one, and the score is updated on the page. The score is initially set to zero. You can replace the `emozi_all/pikachu.png` with your desired Pokemon pictograms.
To play the game, simply open the HTML file in a web browser on your smartphone and click on the displayed Pokemon image to catch them and increase your score.
