This is just a guess, but I think they chose this art style because this story is in the same timeline as The Windwaker. The kingdom seems to be on the decline (maybe just before the godesses flood it?) Castle Town from Ocarina has the same layout and is now in ruins, and there are Koroks.I wish the art style was more like twilight princess but oh well.
The game still looks good
Before Skyward Sword?Dis game timeline is before first Zelda.
