Well that's the way it goes, you know. You can't please everyone, so don't even try. Just try to make a good game, that's all.
I agree with Stogi. I think the wall-link mechanic could end up being really good. It might lead to some level designs that we haven't really seen in a zelda game before. For instance, if I hadn't seen it in the trailer, I would never have guessed that you could sneak out of the barred window to get outside. I think it would be really cool if we see it used for more than just traversal, like boss fights. Or if the wall already has drawings on it, you can interact with those drawings. Like, maybe you are in the wall, but the wall has water drawn on it, and you can't cross the water. Maybe even enemies that can go in and out of the walls just like you can. There's a lot they can do with this mechanic. Don't write it off so quickly.
