I'll reply to all of you that told me to use strict and warnings. I am doing that, and my code runs without errors or warnings the first pass. I also have lots of lexical scoping throughout my code, but I couldn't think of a better way to keep the variables I needed so I could use them in all the various subs and such. I tried passing paramaters and other things like that, but I kept getting 'unitialized' errors, so I went back to the global way. I have read perlintro about 50 times, and lots and lots of other documentation, but I'm still learning and making a lot of dumb mistakes. BTW, this game is not finished, and I haven't added in most of the data that I want the game to keep track of between runs (ex. a word list and related logic).

Obviously this is a case of not enough code, so here is my entire script: 

use strict;
use warnings;
