Use the arrow buttons on the left to rotate and the ones on the right to move your submarine. Press the space bar to bring up and put down the map. If you get too close to an object you will see a red dot around your submarine in the direction of the object. You can find your coordinates on the right side of the screen and then match them to the coords on the map. If you crash into an object you will have to start over. Your goal is to locate a shark which has a tracker on it. The tracker on the shark will ping or beep every few seconds and depending on how close you are to the tracker it will beep more often. Inspired by Iron Lung. But I made this for school.
