I played a little bit of this a couple weeks ago! Got to the surface and did the first little quest where you have to find the penguins.
I remember thinking this back when the game came out: if you go in expecting a Zelda game with lots of exploration and mystery, you're going to be extremely frustrated. But if you embrace the game as a Mario Galaxy style string of linear levels, it's pretty fun.
But again, I haven't played it in a couple weeks, so clearly it's not gripping me, haha. But I've already played it before too.
It's a really clumsy game with a lot of heart. All the stuff with Zelda in the beginning is cute.
