# Mission: Coding a classic `Nsew`
# (pronounced NessEwwh   ;-)
# Nsew is designed to be as easy to understand as possible, yet still be interesting enough to play.
# Project: https://github.com/Python3-Training/Coding-w-Nagy

'''
The Game of Nsew
================
Objective is to see how many "risks"
(moves into unknown regions) we can
endure before being "zeroed," or
scoring less than zero.
