You press the green flag and then press up, down, left and right on the keyboard to move the panda. The panda cannot touch the maze and the astronaut, otherwise the panda will go back to the starting point, but the panda can touch the earth. If it touches the earth Scores will be added, and hitting the earth will also help the panda reach the finish line. The end point is bamboo, and points will be added when you encounter bamboo.
