Bro, I'm not just saying this to you but to all game creators: stop releasing games with zero content and calling them demos. That's not a demo at best, it's a trailer.
What you want from a demo is feedback on the gameplay, the game mechanics, or at the very least some bug reports. But here, what do you expect people to tell you? There is no actual game just three dialogues with no consequence at all, no matter what choices you make.
I'm not saying your project won't turn out great it might be! But for now, there's no way to judge it because it simply doesn't exist yet. The artworks are cool, and that's the only thing I can really comment on.
