Sure! Here's an example of an HTML game featuring a Pokemon pokeball salesman:
In this game, the player can click on the "Buy a Pokeball" button to simulate the purchase of a pokeball. The pokeball sale is then processed, and a random outcome is generated (catching a rare pokemon, the pokemon breaking free, or missing the pokemon). The outcome is displayed using the `showMessage` function.
Please note that this is a simple implementation and can be expanded upon to include additional features and improvements.
