ゼルダの伝説：神々のトライフォース
The Legend of Zelda: Triforce of the Gods

Now that Link has the Power Gloves, he can reach many new areas. One of them is a lake where he meets the head Zora...

With the ability to swim in deep water, Link can reach even more new areas, such as the cave hidden behind a nearby waterfall...

If Link throws something, a faery will appear and, if he admits to having thrown it in, will improve certain items. The boomerang upgrades...

Link's previously blue boomerang is now red, sparkles when thrown, and also has the listed improvements.

The faery will also upgrade Link's shield, with the same generic upgrade dialog as for the boomerang.

Link's shield is now bigger, fancier, and red. It blocks everything it did before, plus ordinary (small) fireballs, but not the oversized variety.

The faery will also fill empty bottles with magic recovery potion, free of charge.

Exploring elsewhere, Link finds an island cave in the middle of Lake Hylia...

It only gives a (mostly) meaningless luck forecast until Link throws a hundred rupees into the spring.

I recently found a claim that the luck forecast actually does have a slight effect: The worst one causes the next ten kills that normally might or might not result in an item drop to definitely drop nothing, while the best one conversely causes the next ten kills of that type to definitely drop something.

Every 100 total rupees, a faery appears and offers a choice...

Fill the amount in the blank. Link starts with a capacity of 10 and each wish increases it by 5, except that the final increase goes from 40 to 50.

Fill the amount in the blank. Link starts with a capacity of 30 and each wish increases it by 5, except that the final increase goes from 60 to 70.

The faery appears again with the same offer for every additional hundred rupees. If the selected carrying capacity can't increase any more:

Elsewhere, a man is camping out and resting in the shade under a bridge...

He hands Link another bottle. It couldn't hurt.

Link can now climb Mount Hebra thanks to the Power Gloves, letting him close in on the final crest in the tower at the summit. While passing through the caves, Link encounters a lost old man...

As Link continues, the old man, who seems to be quite familiar with the caves, makes occasional comments.

Going by context here and in other places I've seen the term, 魔法陣 seems to refer to the intricate symbols inscribed for the performance of certain styles of magic. I can't think of a better term for them, even though there probably is one. The pentagram is one of the simplest examples.

The full purpose of the mirror is explained later.

The old man enters another cave, avoiding the falling boulders on the face of the mountain. Link follows him in to find a modest but livable dwelling.

The old man recovers Link's health, and Link proceeds onward. But when the tower is finally in sight, the mountain becomes too steep to climb any further. It's too soon to give up, though. One of the smaller caves has another telepathic tile:

Spectacle Rock has to be the glasses-shaped rock near the summit. From atop it, reaching the tower would be easy. The problem is how to get up there.

A little more exploration turns up something interesting: There's a shimmering blue tile in the center of a ring of stones. Link tries stepping on it... the screen blurs, fades to white, then fades back in, leaving Link is standing in the same place. Sort of. There's no sign of the shimmering tile, the ring of stones is now a ring of bushes, everything looks more barren, the tower to the north glows menacingly, and let's not forget that Link has mysteriously transformed into a humanoid pink bunny, which is particularly problematic since he can't use his sword like this... or shield, or... much of anything, really. He can't even lift light objects. At least he can still walk around. There are two strange creatures nearby. One looks like a ball with legs and eyes:

ゴロン is the sound of something heavy rolling. コロコロ, the "sound" of something changing frequently (like his mind), is also the sound of a small round thing (like a ball) rolling. Unlike in the US version, ball-guy makes no mention of why things are as they are... probably he has no way of knowing.

...and there's also a creature that looks like a human-sized oni (ogre is close enough if that doesn't mean anything to you), who is kicking ball-guy around:

Interestingly, Spectacle Rock doesn't exist in this world. There's just flat ground there. Link stands where Spectacle Rock should be and uses the mirror... there's a transition just like the one caused by the warp tile, and Link is back to his original world, in his original form, and standing on top of Spectacle Rock! A small distortion remains, which Link can use to go back to the other world if he so chooses.

Not far from the tower, there's a tablet inscribed with a message in Hylian. Link uses Mudora's Writings to read it...

Not very useful now, considering Link doesn't have the Master Sword... Still, it's something to remember.

The tower has a more open layout than the previous areas. Large centipede-like creatures wander around randomly. On the higher floors there are squid-like monsters that bounce Link away when he hits them. Most floors have holes in the floor that lead to the floor below, and some of these holes actually change position when Link steps on star-shaped tiles. Finally, this area introduces crystal switches, which alternately raise and lower orange and blue barriers when struck.

Just inside is another telepathic tile...

Several floors higher is another telepathic tile...

The chest with the Moon Pearl is in plain sight but out of reach. Link must shift the holes in the above floor and jump down to reach it.

The boss, found of course on the top floor, is a giant armored centipede-like monster. The only vulnerable point is the tip of the tail, and striking the head knocks Link away, which is a problem since there are holes all over the floor. The sword is to be the only effective weapon, but this isn't a problem since the boss can't handle many hits. It moves faster when near death, and recovers full health if Link falls to the floor below, but isn't really dangerous so much as annoying. When slain, the boss drops a heart container as usual, and a red pendant falls into the middle of the room.

On the way down, Link stops by the old man's cave.
