I missed #5, I'm not sure I've noticed that, now I wanna go check if my game has that. Is it fixed in any later versions or anything?
And #6 confused me for a moment, what "dungeon songs"? You could've said the songs you play or something, I was thinking soundtrack for a while.
Btw, about #4, (I didn't read the whole thread, if anyone's mentioned it yet) the pillars on Termina field, the ones at the entrance to Ikana Canyon, they have a similar design to the blocks. They also have the Triforce on them.
