whenever you touch the shark or hippo it will say that you killed your penguin, when that happens you must start over by pressing the green flag at the top and start over from level one. However if you touch the orange it will only bring you back to the beginning of the level you are currently on. When you are on the top of the water you can only go to the right not left so if you go too far forward you cant go back again until you jump and then it resets it and you can go both ways until you go up to the top of the water again and then you can't go left once again nor in the air. Make sure you are careful! All the rest of the rules are in the game, on the starting screen press the controls button at the bottom right corner and read them, and when your done press the O.K. button at the bottom right corner. ALL LEVELS ARE POSSIBLE! (but not all routes are)
