Marooned on Alpha 7

Welcome to Alpha 7, an alien world located 337 light years from Earth deep within one of the spiral arms of our Galaxy. It's the year 2533 and your space ship has crashed on this jungle like planet that is covered with many rivers and waterways. Your only transportation is a uniquely designed multi terrain vehicle that you use to cross over many obstacles. Use your knowledge to place objects in the water to help you cross over this unforgiving terrain.
