Zelda 64 - Demon's Quest (hack)

Zelda 64 - Demon’s Quest is a gameplay mod (by Thinedave) that aims to make the game more challenging to the experienced player.

Features include:

New enemy attacks

Trial of Courage: A Savage Labyrinth-esque gauntlet of enemies required to obtain Double Defense.

RPG style leveling: Strength, intelligence, endurance, and luck will bolster your stats in combat.

Hero Mode: Challenge yourself in this mode where damage is tripled and drained heart containers can no longer be recovered. Ever. Try not to lose them all.

Shield Durability: Consider dodging. Shields can be re-bought at a shop.

Perfect Block: Don’t want to lose stamina? Don’t want to lose durability? Don’t want to take damage? Now you can have it all.

Stamina: Every combat action you take drains stamina. No longer can you mindlessly swing your sword about and win.

Life Drain: Upon death, a heart container is drained from your life. Consult the Great Fairies for aid.

Double Damage: Those Deku Babas aren’t playing anymore.

Potions: Drinking a potion no longer pauses the game.

______________

Two known details to take note:

1 - Deku nuts are forbidden and unobtainable, as they could break the challenge. However, there's a very specific place where some deku nuts can be found once. Use it wisely (i recommend using in Jabu's belly, if you find them), these are the only ones in the whole game and it can't be refilled.

2 - there is a chest right in the middle of the Well dungeon. It can softlock the game, but it gives some ruppes, so it can be ignored.
