Haha! Yes, the Great Bay Temple is WAY harder than the Water Temple. I mean let's start with the boss. Who's going to object that Morpha(Morpheel?) was easier than Gyorg was? I actually DIED fighting Gyorg. Now that's something rare to say about the 3D Zeldas. Next, the whole dungeon structure/design. This dungeon really squeezed out every last bit of brain power just to finish the first part. Due to my inexperience in Zelda, I needed to use the Caleb's walkthrough in order to complete it. This might be out of topic, but the dungeon made me use the Zora's ability to jump much more. It was embarrassing that I didn't know of the Zora's jumping ability until I watched the walkthrough. Yeah, but anyways back on topic. The different pipes did help you out a bit. It led you to places, on which where you should go. But after that, you just don't know where to go. If you've played Majora's Mask, I'm pretty sure you know what I'm talking about. This dungeon just punishes you in every turn. That's all I have to say.
