Errr... I assume a passage is basically a section of text (could be one paragraph or more) dedicated to a particular topic or subject, correct? (Sorry, I'm not a native english speaker so I had to google it. I know some terms when it comes to writing but others elude me.) From what I've gathered, there are short passages and long ones. The former can be as simple as a single sentence whereas the latter can be as long as 4-9 paragraphs.*
The story and events happening in your demo felt neither dragged nor confusing, so I think you're fine on that front.
