I. Love. This. Game.
It plays smooth and I love the style. There's a few downsides, for one, being a bit that you're not really given a reason to wreak havoc around this place, but I don't mind since I love being a goblin. You also don't really have any variation in where/how you can mess with the villagers. It would be cool to have some patrolling villagers carrying around jugs of water or crates of food making them trip over and giving you bonus points, or having destructable environment props. (Maybe something for the future?)
To be honest, I'm just nitpicking at this but it's so much fun to play. The real complaint I can only legitemantly say is that there's only one level, but that's a good thing.
