It's not just the linearity, it's also the repetitiveness of it since you essentially have to go through each zone twice to reach the second set of dungeons in each world. While the game is likely just as large as TP or WW, it feels smaller by comparison because so many assets were re-used. I also feel the swordplay focus of the gameplay severely limited the types of puzzles and bosses in the game which are often the two aspects most people love about the franchise. Lie what it does, it does well, but I often can't help feeling like the game needed more time to really expand the concept out. I wouldn't be surprised if the game actually got rushed out considering it was released in an anniversary year.
