Contrary to what Ocarina of Time 3D version did, Majora's Mask 3D improves the artistic style by a lot (except for the moon design). However, the original experience has been unnecessarily ruined by changing bosses and mechanics that already worked perfectly in the original version.

It still makes for an amazing Zelda game, and as long as you haven't played the original, you won't notice nor care about the changes made in this edition.
