Thank you for providing the details for the spelling game! Based on your description, I have created a single HTML file containing the game. Here is the code:
To play the game, simply copy the above code and save it in a file with a `.html` extension. Open the file using a web browser, and you should see a window with floating and spinning letters representing a word. Click on the letters in the correct order to form the word. If you select the wrong letter, a message will be displayed, and you can try again.
Please note that this code assumes the use of modern web browsers that support CSS animations and ES6 JavaScript syntax.
