Sure! Here's a simple game implemented as a single HTML file using JavaScript. It can be played on a smartphone and utilizes pictograms to represent the game elements. The objective of the game is to catch all the existing Pokemon to help the player find a girlfriend.
To play the game, open the HTML file in a browser on your smartphone. The game canvas will display the player as a blue circle. Catch the Pokemon by clicking on them, and once all Pokemon are caught, a message will be shown indicating that you have found a girlfriend.
Note: This is a very basic implementation, and you can enhance it further by adding more features, levels, animations, and graphics as per your requirement.
