Not sure if it's me, it says NaN above the title, and the button that says "Bend!" or "Straighten" doesn't actually do anything. I've tried multiple hard refreshes.
This happened to me, too. You have to scroll down to get the Bend/Straighten button to work. Basically, the visuals on the right side of the page correspond to what part of the instructions you have scrolled top the top.
