This is a hunt the wumpus clone with each of the caverns implemented as functions, dynamically defined based on which chamber you're in. Call an individual chamber's function to move to that chamber.
Once you have determined which chamber the wumpus is in, call the shoot function with the symbol of the chamber the wumpus is in.
The game is played in IRB. Execute ./wumpus in the directory to clear the screen and play the game.
Running Mac OS X, open up your terminal (Macintosh HD → Applications → Utilities → Terminal). Type in
cd ~/Downloads/Hunt-the-Wumpus
and press enter (assuming you downloaded this to your downloads folder). Type in
./wumpus
and you should be running the app.
