So, Majora's Mask. It's still my favourite 3D Zelda... the N64 version to be precise. Forgive me as I have a tiny little rant, it won't be long.
To get this out of the way: the infamous Zora swimming didn't bother me that much to be honest, it was fine and I can see why they did it (to match the way the Goron Mask handles high speed). This didn't bug me much.
What did bug me though was the bosses. Why in the heck did they make every single one of them easier, and in the case of Gyorg and Twinmold, tedious as [tornado fang]? The changes served to make the bosses less fun. I'm not sure if they tweaked anything for Majora, but he felt easier too without the Fierce Deity Mask.
The Ice Arrows... why confine them to specific patches? I understand the reasoning, but it limits their use by far too much. It went from being an item I liked to mess around with to an item I only used in specific spots. Lame.
I did like some changes though, like the Song of Double time. This one takes away a lot of the tedium of waiting in one spot for a while. Guess they decided to have that waiting time to be during the boss fights instead.
