Mr. Dumont does not like to lead a boring life. He dreams of flying around the world in his homemade plane. But, before setting off to conquer the world's latitudes, he should practice. And for this, Dumont will need your help. Watch your flight altitude, don't let it go too high or go too low. Also, carefully fly around all the obstacles. You must control the plane so that Dumont flies exactly through the formed corridor. If you encounter an obstacle, the game will have to start from the beginning. Try again and again until you can fly the maximum distance and reach the traveler's goal.
