The paranoid type. I collect as many bottles, fairies, heart pieces, and other power-ups as I can find before entering a dungeon, especially after I've beaten the first one or two. I take time to practice all of Link's offensive and defensive movements, even if I don't think I need to. I read the manual cover to cover.
If a dungeon looks really complicated, I may read a walkthrough or two before trying to beat it.
I'm pretty good at solving puzzles that involve something hidden. A hidden door or a hidden switch, or something invisible? You won't be able to hide it from me, even if it's very well hidden. I'm also pretty good at defeating and blocking normal enemies, even Darknuts.
My weak points would be areas that use a timer, situations where one mistake equals failure, areas that involve sneaking, and sequences that make you start over from the beginning if you save and quit during them. I also have a strange tendency to overlook things that are too obvious, because I'll think it's a trap, or fail to recognize the significance of it. Often, it's something that's so obvious to most people that it's not included in a walkthrough, that trips me up for months.
