Sure! Here's an example of a simple animated game in a single HTML file that encourages reading habits by promoting book reading. The game is designed for smartphone operation and uses pictograms. It displays a book cover, and when the cover is tapped, it reveals a random book recommendation with a short animation.
To use this code, save it in a file with the extension ".html", and make sure to replace the image URL `"emozi_himawari.png"` with the actual image URL of a book cover you'd like to use. You can add more book recommendations to the `bookRecommendations` array if needed. Simply open the HTML file in a web browser, and you can enjoy the game by tapping on the book cover to reveal a random book recommendation with a fade-in animation.
