It's a bit hard to say much about the game, because it's still so little, but from playing the demo:
1. It looks pretty good. Maps are decent, although a little big, and can make walking around feel a bit slow, or even tedious at times. Like when I went into some corners of the town map, or into the side rooms in the water building.
2. I liked the detail put into what you have so far. Little things like giving shopkeepers different dialogue depending on which side of the counter I'm standing. Dialogue itself is also nice. The main character seemed a little confusing to me (as in being very cheerful when killing a guy), but I guess that makes it more interesting.=P
3. I'm not sure what the point was of giving my opinion on the town, but I'm guessing it changes the background song depending on what I choose. Again, I'm not exactly sure what's the point in it, besides giving me choice in what kind of music I want to hear (which isn't a bad thing I might add).
Also found it a little hard to judge the town right from the start; maybe add a small overview cutscene of the town the first time entering it so the player can get a better opinion.
4. I felt the tutorial was a bit out of place, but I guess that's part of it being a demo. It would be nice if the tips could be implemented in a way that they are presented during gameplay when the player actually needs to use a certain feature for the first time.
5. I felt the battle with Recht dragged on for a bit too long, maybe cut his HP by a small amount (20% maybe). For a fight that wasn't in the least bit challenging it didn't need to take that long to finish.
6. Small nitpicking, but the floating island appeared to be really flat. Maybe give it a few more layers of dirt.
Overall, I think you have a solid starting point for a game with your current demo. Map-wise I felt it was alright, if not slightly large at some points. Graphics-wise it looked good, but I guess you were using the RTP? (lol, I'm not familiar with VX Ace RTP). Choice of music also seemed to fit well.
Would be fun to see you make some progress with this game.
