In addition to ww's suggestions, you may want to choose an easier to read and more maintainable way for allocating resources according to difficulty level. Instead of all those ifs/elsifs, maybe try something like:

#!/usr/bin/env perl use v5.10; # or later! use warnings; use strict; my ( $diff, $wood, $food ); $diff = "easy"; #consider given/when instead of ifs... given ($diff) { when (/easy/) { $wood = 120 ; $food = 50; } when (/hard/) { $wood = 75 ; $food = 20; } } say "I have $wood sticky sticks!"; say "I have $food delicious morsels!"; __END__ I have 120 sticky sticks! I have 50 delicious morsels!

Adding a new difficulty level or resource-type into this structure is $diff eq "easy"; (of course, if you add more resources, you should probably adjust the formatting so they aren't all on one unreadable line...)
