A technique returning from the original Majora's Mask, the Long Jump is a forward jump that makes Link travel further than he is supposed to. Doing this allows for many skips and timesavers by traversing over large gaps not normally jump-able. It can be combined with the Zora Mask to reach even higher ledges. Compared to the original MM, the distance gained from a Long Jump is much bigger, allowing for various skips that otherwise would require hovering, making it much more useful.
Alternatively right after placing down the bomb and turning around, equip the Zora Mask. After transforming, tapping A will skip the animation of Zora Link moving down his hands, saving a bit of time.
