Yeah, that's really a strange choice for formatting and makes it very hard to read. Not the typical practice to insert a <br> after every sentence... (that said, the post itself is a great read!)
The goal of truncating the sentences in that way was precisely to increase the suspense a bit, but I believe I miserably failed, making it just less readable.
Definitely not the end of the world - no worries! It just feels a bit uh, haphazard in a way. My eye is leading forward for the next words only to find I need to skip to the next line. I usually read very fast so I'll be a bit more sensitive to variations in formatting like that, I guess? All good though, like I said a great read anyway!
If you have a wide screen, you won't notice it so much. Try reading on a narrow screen in just about the wrong resolution and it will look like the author used notepad and hit enter every time they were too close to the edge instead of letting the program do the wrapping.
