Sure! Here's an example of a text-based game inspired by Iron Man, using JavaScript in a single HTML file:
When you open this HTML file in a web browser (preferably on a smartphone), it will display a welcome message and prompt you to choose a character. Each character option is represented by a pictogram. Based on your selection, it will display a corresponding message. If you select an invalid choice or close the prompt without selecting a character, it will end the game with a failure message.
The game will then show a "Thanks for playing" message, and the page will automatically refresh to allow you to play again.
Please note that while this example demonstrates the structure and basic functionality of a simple game, it can be further expanded upon to include more gameplay elements, levels, and interactive features to enhance the gaming experience.
