I like the variety of movable backgrounds, they adds a bit of dynamism and sense of place to the story! Pausing for choices could be beneficial for faster readers, I didn't expect it as I advanced through the text and picked the default option on my first playthrough. The music is fitting for the tone of the scenes and the text appearance sound effect is unintrusive and adds a nice sense of tempo.
You've got a very distinct style of presentation, it definitely gives the game its own identity and atmosphere.
