51I didn't expect that. Yeah getting through Zelda games is always difficult, but enjoyable
If you really need to, try looking up some guides at some parts that you find too difficult (I needed one for a great portion of the first Zelda). or are just taking way too long to figure out. There are times where I've taken long breaks from a few games just because of how much time I spend trying to figure out one thing, it makes that part of the game unenjoyable for me.
Also, Wallmasters? Common as they are in Ocarina of Time, rest assured they are a minor concern in Majora's Mask. There's actually only two of them in the entire game, and there's only one Floormaster in it as well.
Personally Wallmasters never scared me (they startled me on the first attack, though) but....there was one particular enemy in Zelda that scared the living heck out of me for a long time when I first encountered it. Any guesses on what it is? (it first shows up after a water dungeon in a certain game, so I'm not sure if you'd know)!
