In this lighthearted cave exploration game, you play as someone who was sleeping in their bed at home and woke up in a cave and carrying a rucksack. And there's a lantern nearby. You've had dreams about a cave like this. You should go explore it.
This solution is by David Welbourn, and is based on Release 2 of the game.
SPOILERS AHEAD. Reading a walkthrough prematurely can sometimes diminish one's enjoyment of an interactive fiction game. Please make an honest effort to play the game before reading this walkthrough.
You don't need to ride the horse anywhere, but it's pleasant and you can take the horse everywhere, so why not?

Although it's suggested that a magic word can activate this mirror, I don't think that any such word was implemented.

Concrete room
The description of the door as a "golden grate" is incorrect; the golden grate is elsewhere in the game.
The shadows seem to hint at some hidden meaning, but if there is one, it remains a mystery.

You don't need to obey the sign unless you want to. Feel free to leave the door open and unlocked.

Extras
Characters
A horse is contentedly eating grass at the stream side. You may ride it. (You may also kill it, but why?! Amusingly, if you kill the horse while riding it, the living horse stays underneath you while the horse's body appears in your current location. Oops!)
For completeness's sake:
We're never told who lives in the cottage, in the underground city, or in the home on the other side of the golden grate.
The painting is unsigned, but it does show dwarves, horses, sheep, goats, and dogs.
The statue in the cottage looks like a god, in your interpretation.

a brown Candle. It's in the sitting room.
a Green Candle. It's in the sitting room.

The iron key unlocks the heavy iron door at the end of the sand path.
a Golden key. It's on the hellish path.
The golden key unlocks the golden grate at the end of the steep path.
a brass key. It's in the east end of the hallway.
The brass key unlocks the wooden door at the east end of the hallway. (The wooden door has a brass knob.)
a White Key. It's on a golden holder in the west hallway.
The white key unlocks the white door also in the west hallway.

a Brown stone. Put the brown candle on the brown stone.

Treasures
Just pick up the treasures and keep them. You don't need to put them anywhere special.
a Golden Sword. It's at the bottom of the pit.
Many Coins. They're in the chamber, north of the end of muddy passage.
some diamonds. They're inside the cottage.
Other items
an old rucksack. You're wearing it.
It's your player's carry-all. Keep it on and ignore it; you'll put excess items into it automatically.
a Lantern. It's in the dimly lit room.
Take it and turn it on for light in all the dark locations.
a empty bucket. It's at stream side.
At the stream side, if you put water into the bucket, it becomes a bucket of water. Oddly, you don't really need to take water anywhere.
a piece of paper. It's inside the cottage.
Read it and turn it. It's a clue that you should place the blue candle last.
some apples. They're inside the cottage.
You can't eat them when the horse is present (and alive). If the horse isn't there or is dead, feel free to eat the apples.
a Red fire torch. It's in the concrete room.
It's a light-source, but you don't need it when you have the lantern.
a Brass torch. It's in the east end of the hallway.
It's a light-source, but you don't need it when you have the lantern.
bolts. They're on the silver iron holder in the north end of the hallway.
You're probably not supposed to take these.
a silver blanket and a light blue blanket. They're both on the bed in the bedroom.
Taking them earns you points, but their descriptions don't change.
