# We're going to make an adventure game!
# In the game, you navigate through a maze of rooms, by typing in "north", "south", "east", or "west".
# In each room you enter, the computer will describe your surroundings, and then ask you what direction
# you want to go in next.

# If you haven't already done so, run this program in the PYTHON INTERPRETER to see how the gameplay works.

# So, how to put all this together?
# First, we need some descriptions for our rooms.
