I chose the array mainly for the fast lookup time compared to lists,
are you suggesting something like creating a "Map (X,Y) Health"? I'm
not currently updating any structures, rather creating the successor
from scratch. I can see how the map may work very well for the sparse
nature of non-early life games now that I think of it.
