Loved the visuals! The characters are charming and full of life, especially with their dialogue. I could see some interesting plot developments with the Prince. The dark room segment also really got me. By the time I got to the chase sequence I was panicking to get back. Definitely my favorite part.
The book puzzle in the beginning was a little confusing. The matching part wasn't too bad, but I didn't realize I had to place a book on the desk to complete it. I ran into the Game Over screen several times thinking I was placing the books wrong instead.
Overall, really solid demo. It covers just about everything you'd want from a game like this. Looking forward to the full game!
