The goal is to make it from the starting point to the docking tower where the Cloud Algae can be sold.  The amount of Cloud Algae ready for harvest is dependent upon the weather conditions you move through each turn.

You start with 1 Algae and 6 water.  Each unit of Cloud Algae uses 1 water per turn.  Each sun unit causes a reduction of 1 water, but increases the Algae count at the end of that turn.  You may move one hex/turn, but have three wind counters you can use to move 1 additional space.  The weather icons on the map (rain clouds and scorching suns) give d3 of their respective weather.  Assume for now that you can retain as much water as needed in your Clouds.
