Looking good, princess - especially from this angle!
The original Zelda is very interesting for only directing you towards certain sections. Unlike other games (and indeed unlike the linear style of play it later focused on), Zelda posed puzzles but threw up few barriers to progress. You're free to run through the game without a sword if you want...but it's dangerous out there!
