Underground is a Z-machine and Glulx interactive fiction game written with Inform 7 and is © 2019 by Phlegethon.

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?

This location is a dead end. Head all the way back to the bottom of the pit and go down from there:

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

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.

The response to INFO is:

This is the second release to Underground. The art is done by: ReapersHorror. The intro track which can be heard while playing on Windows Glulx, in the .glorb file is composed by: Phlegethon.

Put each candle onto the stone with the same color, but only putting the blue candle on the blue stone earns you any points.


All the stones are in the Colorful Room. Put the appropriate candles on the stones.


Just pick up the treasures and keep them. You don't need to put them anywhere special.
