Than you probably will be glad to hear that the temple of the Ocean King has been seriously updated. No more repeating of floors, you can just skip them by climbing the winding stairs. And there is no timelimit for completing parts of the the spirit tower.
Yeah Spirit Tracks is a serious improvement over PH.
Why can't they just drop the mechanic altogether, and go back to the dungeon crawling of old? A much better idea if you ask me.
Actually, that still is the basic old dungeon/world exploration mechanic. Because back than, you often needed a key/item to unlock a new area or dungeon. You had to talk to NPC's to find the cave, crawl the cave, get the key and go to the new area.
WIth the spirit tower you talk to Zelda or Anjean, you go to a new part, crawl the new part, get the key and go to the new area.
So basically you do the same as always. You don't even have to repeat the same part of the tower (with the exception of the winding stairs room). The Spirit Tower is very different from the Temple of the Ocean King.
