that's cool to hear! it might be a good idea to outline the events of the demo so you can really focus in on what matters. i think it'd be cool to add some narrative hooks that you can expand on in the full game though such as--maybe there's something dark and mysterious we don't know yet about the character's backstory--or maybe we meet someone who is important to them or perhaps a villain? i think having these seeds for the larger world or narrative planted in the demo will really make people want to play the full game!
