Sure! Here's a basic implementation of a simplified Pokemon game in a single HTML file using JavaScript:
This implementation randomly selects a Pokemon from the `pokemonData` array and displays its corresponding pictogram. When the player taps on the pictogram, an alert message is shown indicating the caught Pokemon, and the game resets to start again.
Please note that this is a very basic implementation and can be expanded and improved in various ways to make it a more engaging and interactive game.
