I liked the story because I knew the story.
The Piper came into town to stop a rat infestation, an infestation that had the people's food and money quickly eaten away from them. The Piper used his music to soothe the rats and led them to their demise by taking them to a river to drown. When the Piper asked for his pay, the mayor had the money but would not pay. So the Piper played his music on the people and led them to their deaths.
Well, that pretty much covers up the whole story of this short animation. Since you didn't put in a short summary what it was about, I bet many people would get confused, and I don't like that kind so far, since it attracts lower scores to people who don't know the story, but at least I hope my summary should clear things up by now. The animation was pretty well made too and I pretty much like your clothes so far. Advertisements in animations rule, haha.
