Help this little man get to his friends, who are having a party quite a bit further on. The little man is equipped with a paint gun, that can spray the colors orange and green. This paint has a very special property: when you walk on it, you accelerate and you can jump higher. So then the little man walks into a high obstacle, he'll first have to spray a path of paint: then, when he walks over it, he's able to take the obstacle. Don't use more paint than necessary!
