Use the keyboard's left, right, up, down keys to control Jaman. You should run Jaman away from devils for his life. In a normal case, devils cannot turn back unless they go to a dead end path or when Jaman is eating a magic orange. When eating a gold nut, Jaman slows down.
Devils slow down on any turn or run in some slow path.
After eating a magic orange, Jaman can beat any devils whose color is changed. Try to eat all devils each time. You will have one more Jaman every 10000 points. You can hide your game and continue after that. Remember to use it in many sensitive cases, for example, when your boss is coming.
