Just finished The Minish Cap, and I'm very pleased with it. After playing Spirit Tracks and Phantom Hourglass, it's nice to play something in the traditional Zelda style again. I enjoyed the Oracle games back when they first came out, and I think this is probably the closest to those.
My favourite thing about the Minish Cap was just how many references there were to all the other Zelda games. It had characters and items from Ocarina of Time, the Oracle games, Wind Waker... pretty much all of them really. I got really excited when I heard the tune you play on the Ocarina, when I bumped into Malon, and when I fought some Iron Knuckles for the first time.
I also liked the massive amount of secrets. Even though I spent a fair amount of time looking for optional stuff, I finished the game missing 4 hearts, 2 bottles and a few sword skills. So I guess I've still got a few things to go back to, but I think I might have to use a walk-through, otherwise it's going to be really exhausting to get everything. I hear there's even a few items I've missed.
Anyway, I felt the game did still suffer a lot from the Game Boy Advanced's limitations. It would have been nice to have more buttons to assign items to, and the sound effects were really crappy. I wish they'd have made a similar Zelda game for the DS, that would have fixed those issues, and having the second screen would be great for the menus as well.
Another issue I had was that it was pretty hard to figure out some basic game mechanics. For example, I spent ages trying to figure out what to do with the sparkly trees and dirt-caves, so eventually I gave up, and when I actually got the required items, I never thought to go try them out again. So I spent a long time being lost because I didn't realize I could finally go into those weird caves I had been seeing since the start of the game. My hat probably should have helped out with that at some point.
Finally, story-wise it wasn't very interesting, but I guess I'm used to that from Zelda games. At least the villain wasn't Ganon, but it might as well have been.
Overall, it's probably my 3rd or 4th favourite Zelda game now, after Ocarina of Time, Wind Waker, and maybe Majoras Mask.
tl;dr: Awesome game, but I wish it were for the DS and that there were a few more hints.
Why am I playing so many video games? Because I have exams and can't have any long-term commitments right now.
