Hi, michan here (again)!
Played the demo! So far it looks nice (though still incomplete). The sprites look good and the CGs go well with the storytelling. The interface is user-friendly, too. Exploration is a nice feature and I'd love to see how it would be implemented in the full game. It's also good that you added a notification regarding the qte feature (forewarned is forearmed, yes?).
As to what could be improved, I'd suggest getting a proofreader/beta reader for grammar/typos (wondering-->wandering, 'trying to be patience'-->patient, etc.) and to mitigate the redundancy in the text, such as:
'grant your wishes' and 'makes them come true' --> choose one of these phrases as they're pretty much the same
'they're not familiar with the place' and 'a country that they've never been before' --> Maybe just write it as 'It was a strange place; nothing looked familiar.'
Also, plotwise, is there any reason for
Yuyuko and Silver NOT to call the police or send Dan to a clinic or hospital instead of taking care of him at the inn?
I just find it curious, but if there's a twist... then <3
Would also like to hear more music in later releases of the game!
