I notice that on tall screens, the text spills off the bottom and isn't scrollable, at least with Chromium. I zoom out, but on some of the longer screens it's pretty hard to read. I think I've seen that on other Twine games. If there were a way to enable scrolling that would be helpful.
Edit:
I finally got to a screen that was too small to read zoomed out (steve escape), and resorted to devtools.
html body #story { height: 100%; }
#story { overflow-y: scroll; }
Only this doesn't include the "Continue" link that appears on some screens. For that I had to zoom out.
