Read about this on RPS the other day, downloaded the demo and then bought the full game before finishing it. Looks wonderful.
I'm thinking of recommending it to my sister, who loves Plants vs Zombies and I'm sure would dig the art style. However, she has Views about the portrayal of reptiles (snakes and dragons especially) in popular culture (the Bible, Harry Potter etc). If you have to slaughter lots of them to progress, I'll send her elsewhere (this was somebody who made me deal with the Weighted Companion Cube in Portal).
I'm looking forward to completing the main quest, so would appreciate an answer without spoilers
