I spent 3 hours playing this. xD I think the art is really good, the only thing that really bothers me is that the voices come our every single time I click on something. Although, since a lot of games are like that, I suppose that is okay. xD
I do have a suggestion though: You should make a mini map with the monsters marked on it. It can be a hassle to have to run around trying to look for one monster you forgot to kill (so a map would be very useful).
