I am currently working on this game and I have finally beaten the first 2 dungeons. I am on my way to the 3rd. I plan on beating it within this next year for sure. (I have a wife and child, so it is a little hard to put in the time). I will eventually beat it though. I am playing this game on the gamecube.
I beat the first palace only so far. That game is as hard as a rock. I wish it was like pokemon, where if you save, you start at where you saved, but too bad that you can only save when you Game Over. FFFFFFUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUU
Congratulations! I have the game on my 3DS, but I'm still in the beginning, the enemies are really hard to attack since they keep on moving around a lot. I wish I can beat the game. I'm working on it but now you sir have inspired me to continue to play Adventure of Link. Again, congratulations on your achievement!
