Micro Submarine

You are a marine scientist. Your mission is to chart the bottom of the ocean so that it will be easy for your group to conduct experiments later on. No, you are not deep diving to do that; you have been equipped with the latest in charting technology: a micro submarine, so mall that it is not even larger that the average rock fish, and yet have the ability to record a very wide view of the ocean floor. Now all you have to do to create the chart is to keep the submarine moving along the already defined path. Just keep in mind that the submarine, being at such a small size it is in, is vulnerable to all sorts of dangers. You have to avoid marvel fish, electric eel, explosive boxes used by some nasty fishermen and bio hazard dumped by some irresponsible factories. Each hit will take off one hit point and if all hit points are depleted, the submarine will be ruined and your charting mission stopped. However, there are also some bonuses that you can collect along the way. The bonuses with $ will add to your score while the bonuses with + will add to the submarine hit points. The bonuses with >>>> will increase the speed of the submarine but only for a limited time.
