Wow, this was such a fun demo to play! Excited for when the full game comes out. As for the questions...
Q1: Most likely Vicenzo's route. His character appeals to my own personal preferences, (romantically.) and from what I've seen so far, I'm very curious about the rest of his presence in the game.
Q2: I loved when Vicenzo led the MC to the artifacts and whatnot underground. I'm the type of person to get really interested in a game's plot, and that scene felt like getting to eat a five-star meal after looking at a menu full of delicious options. (for lack of a better analogy.) I also really liked the romantic scenes with Vicenzo! They made me more interested in his overall character, as well as how the relationship between him and MC would progress.
Q3: I'm very excited for the game to be released, and will probably buy it when it does. Can't wait to see how it comes out!
Q4: Very much so. I think the best type of villain character is one that isn't outwardly abrasive or open about their true intentions. Sly and charming types of characters are some of my favourites, and I think you hit the nail on the head with how Vicenzo acts. As for Edel, I can definitely see his appeal. I would be excited to see how he acts more in the final game.
Comments: Great job on this! The dialogue was easily one of my favourite parts, along with the art style. I love the watercolour kind of look to everything, it's so pretty! Keep up the good work, and thank you for making it!
