I wish you'd change how some of the words are coming from off screen. The word Betrayal specifically because it's the word that is changing the tone of what you're listing, but because you have it coming from the end of the word it's easy to identify. Not a whole lot of -ayal words. It just ruins some of the intention of revealing the words in the first place, to me. I think Sin should reveal from the front as well simply because for a brief moment I expected a longer word than sin to be revealed. It's a common three letter combo.
I like that music for the subject of the book. Works well
