So I was looking at the route on ZeldaSpeedruns for the glitchless category, and noticed how not helpful the GBT part of it was. I've managed to get longjumps to most of the 'red keys' but the last one, in the lower tunnel, I can't seem to get to without getting ice arrows... so how would I do that?

 Route:

(Forest Ruins) - Get Charge Shot from the cowboy in the Saloon, then do the dungeon as normal (Ninja Cave) - Get Miracle 5 bounty, machine gun and shotgun, do the dungeon as normal. (Red Canyon) - Get revolver in the dungeon (2nd room fall down hole [x2] up [x3] down-left, left [x2] up) then to get back (backtrack to large room, take the southeast exit and follow path to snake room) get coin #1 (in between the two areas of the dungeon, go up the ladder and drop down the ledges to the cave entrance) however, you'll have to go through the entire dungeon again :( (Ghost Town!!!) Get Crazy shot (go to the right of the desert, down the ladder, and up to the screen transition to a house [7-8 hearts required]) , Bounty, Crucifix, to Ghost Town, Iron Fist (3rd house in front row, left, up, right [x2]) then backtrack to normal dungeon route (I'm the only one I'm sure that needs to actually learn Ghost Town) (Abandoned Mines) - literally just do Ghost Town skip, then take the first right you can in the dungeon for coin #2 (Wood Tower) - Deathwarp out of Abandoned Mines, swimming gear, shroyuken, to wood tower, power hand (in dungeon: up-left, up [x2] , right [x2], down) do the dungeon normally afterwards (Stone Tower) No carrot!! by waterfall, go up the ladder and jump off the two ledges, but not onto thee ground and follow path to coin #3, go to town and shroyuken up waterfall (in town) for coin #4 then follow path normally (carrot) but, once you get to the metal shield area, go left and follow that path to above Ninja Cave for the final coin #5 then do Stone Tower... except go (at start of dungeon) take the Northwest stairs, left, down-right, right, up (choose the green suit) do the dungeon normally (Suspicions Mountain) - exactly the same
