Hardest game you've ever beaten?

The game looks pretty interesting to me, but I haven't been able to find a copy of it. I'd probably ragequit before beating it, though!

If you're not attached to physical copies, it's $5 on Wii/3DS/Wii U. 

It can be stupidly frustrating, like Lead said, but once you get used to the mechanics, it can feel pretty rewarding. Also has some funny NPCs, and RPG-like towns where you can get new abilities. I did a second playthrough to see how much I'd improved, and I finished it like 2 hours, so it's mostly getting the hang of that learning curve and knowing what annoying challenges the game will through at you.

Still my least favorite Zelda outside the co-op ones.
