In light mode they are highlighted in green, but in dark mode they're only slightly bolder than the rest of the text. There was a real inconsistency with options too: some cycle when you click on them, some are in a list, some are in drop-down menus.
I had to restart twice because I'd missed an option in character creation before swapping to light mode, and once because on the page you choose your origin (only 1 at the moment of course) it only tells you what the page is for right at the bottom... so I saw some highlighted text and presumed it was a cycling option like the times before. Nope! Took me into the rest of the story. So I restarted only to find out it was the only option anyway.
I agree that the story potential is fab! Could just do with some formatting adjustments to make the experience of reading it better.
