In Unit 1, Lesson "Code Your Own Adventure", in Lesson 1 and 2 ("Confirm", ,"Old enough to play") you use Confirm command. It's fine. But later in Lesson 3 ("Adding some story") you write:
"Print the introduction using console.log. Remember that the introduction is a string, so make sure to keep it between quotes."
But I think user can't normally see texts from console.log command. Maybe is better use Confirm command or Alert? Is it some mistake with console.log there?
