This is a pretty impressive use of the level creator. I'm surprised he was able to get as close as he did to the actual layout. I'm not sure how he managed to duplicate how vertical that stage is. Pretty wild stuff.
Love that its scalable from top to bottom, seen so many stages that try to go vertical but as soon as you come down from the top level you can't get back up.
That's pretty cool, though the title confused me and made me first think it was the Hyrule Castle stage from Smash 64 lol (The stage this is based on is usually just called "Temple" in the Smash series)
