Are people meant to learn WoofJS only with the help of a tutor? I tried starting the first “Star Catcher” tutorial and, first, noticed that the “full screen” links are all broken in Chrome 72. Over in Firefox, I could view the demos, but I don’t see how to view the code, nor do I see instructions for creating the code. Maybe it works better when logged in, but I didn’t feel like creating an account.
