Glad the dots work for you now, no I wasn't able to work on the game yet, and thank you for the misspelling in athlete in the intro, will fix that.
When you write incorrect character(s), you will have to delete them by pressing the "backspace" on the keyboard, think of it like you are typing the article on a document, and the more red (incorrect) letters you write the more you have to backspace them, someone also mentioned this makes it extra hard, so i might add in the future an option that doesn't punish a mistake that much. I really hope you were able to enjoy it still.
