The story's beginning isn't really original; you are a furry detective called to a small village in the middle of nowhere to investigate on claims that there has been a witch around those parts. Most of the people aren't too thrilled by your arrival, so it's up to you to gather scraps of information here and there to try to piece the story together. After the humble beginnings of episode 1, episodes 2 and 3 really take off and offer a quite original story which is most pleasing to follow. Of course the very nicely drawn graphics and soundtracks add to the experience a lot.
My only gripe is that episode 4 was a kind of a let down, after all this build up. Still, it's free and I can't argue with that - plus the quality is overall outstanding!
