Sure! Here's a simple game implemented as a single HTML file using JavaScript, following the given requirements:
Inflating Girl Game
Start typing and see the girl respond!
In the above code, we have a simple HTML structure with a heading, a paragraph explaining the game, and an image tag for the girl representation. The JavaScript code listens for keyup events and calls the `showResponse` function. The function checks if the user input is empty or not, and updates the girl's image accordingly. You would need to have two image files, `emozi_all/game.png` and `emozi_chicken.png`, in the same directory as the HTML file.
To play the game, simply open the HTML file on a smartphone, start typing, and see the girl inflate when you enter text.
