From an email I received today:

Hello - My name is Luke and I played Legend Of Zelda when I was in my teens. Now I am in my thirties and I really still like to play the game. I see it was officially released for Mac, so I downloaded it. I played the quests from the original game. I then had a glitch happen in the second quest. I went to select the whistle and teleported to the different levels. When I teleport to level 7 I get stuck on the left of the screen. I found out you were involved in the programming of the Mac build. I wanted to e-mail you about this glitch to let you know. Thank you for reading my e-mail.
