I just started seeing things about this hack, and it looks amazing. There are multiple game mechanics added that vastly improve and modernize the format for gameplay.
Right away, we're greeted with this screen to inform the player whether they're using an appropriate emulator to play the game on, so I thought I'd include that screen to avoid any emulator issues.

There's a Hero Mode if you're up to having a more hardcore experience.
Well, that's different.
No longer do you have the luxury of saving from the main menu at any time, opting instead to reach these Save points in order to record your progression and also..
You use them to level up! You are given a range of stats to assign points to right at the very beginning.
Also, it seems that in this game you climb much faster than in the original Ocarina of Time, taking a lot less time getting up or down cliffs and walls.
There are apparently perfect parries in this game, and from what I gather it seems to be worth going for!
You can sprint very, very fast in this game. It may be possible to sequence break in ways players may not have discovered through making longer, faster jumps.
Seeing a stamina bar in this game is an entirely new and different experience. It will be something to have to manage during regular gameplay as an added mechanic.
So, any thoughts on this hack?
