Harder than simple

Often, there are multiple equal length paths to the enemy with different starting directions. The author's preferred logic for choosing one path over another was not explained in the story. I think this mission could be improved by including this logic in the story. Rather than let the student figure out that cubic coordinates are the right approach, why not state that up front and use this mission as an opportunity for the student to develop their own cubic coord system in the code. This took much more time than other 'simple' problems.
