Majora's Mask is genuinely not a difficult game, it just takes time, effort, and memorizing.
If you are not aware, Majora's Mask plays quite differently than Ocarina of Time, it takes place over the course of three days, 72 hours from what i remember. now at a certain point in time, Link gets a notebook that organises his trip. all he needs to do is talk to people to have them filed into the notebook. the game does have na interesting begining sequence before the first dungeon though in that you have to actually go through all 72 hours and await what is beleived to be the end of the world. at that moment you gain the ability to travel through time, now this item has quite a few purposes, and like the NPCs in this game, you saw it back in OOT.
Spoiler The Ocarina of Time...oooh time is a real hint
now you can travel forward, slow time, or go back to what is called Dawn of the First Day. when you go back to Dawn of the First day, you basically save your game. as a consequence, you lose all ammunition, any rupees you have in your inventory, bombs, deku nuts, and anything that is considered temporary, permanant items stay! things like masks, bottles, and other items that link keeps stay as well, upgrades stay with you as well. but those really arent problems if you know where to look.
gameplay really isnt bad, it just takes planning and thought, a bit more than OOT did. i also loved how open it was with mini-quests and some of the back-story behind Ikana canyon. i saw more in MM than i did in WW, i'm not kidding.
