Some good ideas.
Overall, it was a bit bland. It played like one of those old half-baked in-between program animations on the kids channels after school. But some of the ideas in it were great. I liked the puddles for one.
What i would have loved to have seen is the interactivity actually affecting the story. I really wanted the end of the story to somehow tie in with the stepping in the puddles for example. A bit like a choose-your-own-adventure story, but more spontaneous. So the ending would always be roughly the same, but have different touches, depending on what you interacted with while watching. I'm sure for what's expected in terms of your assignment, this will be impressive enough, but if you build on this idea, you could make something really awesome indeed.
