There is one thing Nintendo has shown lately hasn't been a disappointment! 
Looking closer at some of these layouts...it appears that Zelda, at one point at least, kept score and had a timer? Also some sort of 10-item grid at the top of the screen?
Top-right map had some interesting stuff...looks like there were thoughts of a dragon or other creature that slid in and out of a block, similar to a Piranha Plant? Kinda wonder what the Japanese on that map means.

Very rough translations.
Note: The term ニョキ more or less means 'stretch'.
"(The hands) will stretch out and pull you towards the wall."
"Will stretch out from the holes. Snakes, turtles, dinosaurs."
As the game was earlier supposed to be much more linear (no overworld, just dungeons), the score and timer isn't surprising. Very cool images.
