Amazing demo! I applaud your work, Knightmare! It is nearly flawless in design, however, I did find just a couple of errors:
*After the battle with Gohma, when you recieve the Kokiri's emerald from the Great Deku Tree, Link will be unable to use any of his weapons, even if you set them to different buttons in the menu. I have found that diving into the deep water near the shop can reactivate weapon use, however.
*It seems that Gohma larva can still fall outside the room via the part where the closed door is.
*This isn't really an error, but when Link is being teleported out of the Deku Tree, he stops at the wall, making the illusion of him floating upward foiled.
*If you throw an object (i.e. a pot) while you are facing downward, but have a wall directly behind you, the object will hit on the wall behind Link, and break on the floor, instead of being throw away from it. I know this may sound a bit confusing, but you'll see what I mean when you try it.
Otherwise, this demo was great! Keep up the good work!
