It's the building of the game around it. I've always believed that the fundamentals of Zelda are that people want to run around and hit things with a sword. Mr. Aonuma has done everything in his power to ignore that, with a puzzle focus, with a cinematic focus, with having up to two hours of gameplay before you're allowed freedom with a sword. 

I'm honestly fine with it being a small mechanic for some levels. Like say controlling a ball was in Mario Galaxy. Also the difference between this and a brick-staff is that the latter is another player option in all situations (i.e. would this tool work here) whereas I expect the painting to be highly modal and restrictive of options. Obvious entry points with flashing signs; much more limited options while in it; and no choice but to use it to proceed (compare something like Yoshi, which was never needed in SMW to proceed). Exactly the same thing about trains and boats by the way.

When he says we should change the formula of Zelda, he's thinking people are bored with the last gimmick and they need a new gimmick. I think that with gameplay solid enough you can make the same game over and over without people getting sick of it.

You expect it to be modal, fair, but let's give it a chance. I'm more imagining something along the lines of it being a Stealth Option.

Sure. If it's downplayed or different to what I expect I might even pick it up; it's otherwise the 2D Zelda I've asked for.

Add a difficulty setting right after you create a new save file. That would be an unexpected element that would be completely welcome.

Edit: I feel so strongly about this, I posted it twice!

I'm not too worried yet: the playable dungeon didn't have any such flashing "use ability here!" indicators that I noticed. Plus, I can see the move's utility in dodging enemies, especially in tighter quarters. Although I assume there'll be some enemies that can get you even when you're a painting, or else combat risks being too easy to skip entirely.

Unexpected? How about switching from Link to Zelda at key parts in the game? That'd be interesting.

Go home noname, you're drunk.
