This reminds me a lot of the typing game "Paint by Letters" in Club Penguin. You could probably make something inspired by that with this concept, maybe using other public domain books or stories of your own.

Thanks! Yeah, more stories would definitely improve it. Originally it read from a local file book.txt, but to package it for web I had to package it in the export but ran out of time for that submenu. I was thinking of improving the game a little and adding optional background music and a book selection menu. Check back again after I add it.
