I believe the current published run of 05:35.93 can be improved upon by at least several seconds. At 4:42 of the video on the screen where Link loses a life, you can advance the screen slightly to the right, exit left, and then exit left again (without moving the screen right this time) to appear in the lower part of the hallway type area with the flying Ras and the blocks that cover the invisible pit going below. From here you can go right a bit and drop down the aforementioned pit after breaking a couple of blocks. This seems much quicker than the route used (which uses fairy to travel through an unnecessary room and puts another death in there to replenish the MP). I'd be interested to hear thoughts on this and whether I might be mistaken. Apologies if my post is better suited in the topic for the published video itself.
