Since you're not asking a Perl question, rather a game design quesiton I'm confused as to why you're posting here. However, so far:
At this point I've pressed one button, this one decision has resulted in all the action taking place. I'm now level 9 for deciding to play the game by pressing '1' rather than the script dying at line 120 with an "uncaught exception" (which occurs when you select "2" rather than "1").
The game lacks any real user involvement I've experienced with other text based RPGs. If you want it to be interesting for people I suggest more user involvement, less automated actions. Perhaps you should check out some other games of this nature and see how they engage users.
Update: Added option "2" explanation.
