Taking a detour via the bomb shop (for a Super Bomb) and then the hole I made in the Pyramid wall (to get to the fairy inside, who gave me upgraded arrows and the Golden Sword), it was off to Ganon’s Tower.
And it’s HUGE. And, although not especially difficult (yet), you need one hell of a lot of magic for it. Which I didn’t have. So, about half way through the tower, I was stuck. I couldn’t go forwards (as I needed magic to open a door) and couldn’t go backwards (as there was nowhere else for me to go, and no magic to collect). So I saved and quit instead. Tch.
