Just watch for most of it, and answer questions. If you forget what the options are, they are Chloe's dorm, the boardwalk, and the park.
I was curious what the new tutorials from Scratch 3.0 were like, and the "make a game" or something like that, seemed fun. So watched the video and used the characters, and it turned out to be more of a "choose your own adventure game". I hope you enjoy!
