The Paper Boy

This is a very special deliveryman: he's made of paper! He rides around on his little bicycle and has to take food from one building to the other. On his way, he picks up all kinds of food, that he has to take to its destination. It's important to avoid the water, because you know what will happen to paper when it gets wet. The paper puppet should also avoid the walls. When he's put the food into his basket, an arrow will tell him where to go. The more food he delivers, the faster his bike will get. How long will you manage to keep up?
