Bug Fixes

I had some of my friends play the game and they found a couple bugs that I have since fixed.

The latest version includes the following fixes:

• The message "You aren't wielding a SWORD!" will now display when you attempt to attack with the sword when it IS NOT in your inventory instead of displaying when it IS in your inventory.
• When used, the KEY will now correctly open the North door instead of the non-existent South Door.
• When you are reduced to 0 hit points, the game will immediately end, instead of after your next action.
• NPCs who are dead should no longer try to attack you.
