[edit] Install

[edit] From the source file

You need Python, Pygame and the Numeric module to launch the game from its source file (under Ubuntu, you need to install "python", "python-pygame" and "python-numeric" with Synaptic).

Once Python and Numeric installed, you can download this file:


and extract it to a folder. Launch it under a terminal window with the command "python moe-pygame.py".

If you want to play the game with no graphics, you can launch the curses version in a terminal with the command "python moe-curses.py". If you change the terminal size, the game will adjust accordingly to maximize the display area. The minimal size for the game to play is 80 columns by 25 rows.

[edit] From the Windows binary

To play Mines of Elderlore under Windows, download this file: http://downloads.sourceforge.net/elderlore/moe_windows.1.0b4.zip and extract it to a folder. Launch it by double-clicking on "moe-pygame.exe".

The game has also been ported under Windows by using Wcurses. To play the game with no graphics, double-click on "moe-curses.exe". The display size of the game is fixed at 80 columns by 25 rows, and cannot be changed.

[edit] Play

[edit] The game

[edit] Synopsis

You are a young hero and to prove your strength, you decide to clean the mines in the forest nearby your native village. Only armed with your training sword, you enter the haunted forest...

[edit] Gameplay

This game is a roguelike. It is turn-based, so you can take all the time you want to chose your strategy.

By moving in the four directions with the arrow keys, you attack monsters, open doors, collect equipment or use stairs (see § 'Keys' to learn about all the keys in the game). Your goal is to survive long enough in the mines, progressing by killing monsters and descending as deep as you can.

As you wander through different levels of the mines, you may find different weapons of different values. Each weapon has intrinsic qualities and drawbacks, and provide different gameplay. Be creative ! Only by chosing the proper weapon in the right situation will you progress deep enough in the game (see § 'Weapons' to know more about weapons).

[edit] Death

Once your character dies there is no loading back: death is permanent, and the only way to go when your character is dead is to start another one.

Yet there is one advantage for following players: they inherit their ancestor's memory, and all levels that were previously explored will be known by the new character.

[edit] Scores

A score is given when you die, that equals your XP points. If you are a winner, your score will appear on the top of the other scores, different winner scores being sorted by the number of rounds they took.

A board of scores and ranks is keeped, and since every dungeon is the same for every player, it should be easy to compare performance each other. If you want to explore another dungeon, just change the 'name' value in 'moe.ini'. If you set this 'name' value to 'random' (without quotes), a new different dungeon will be generated each time, with a randomized name.

[edit] Fights

[edit] Monsters

Demons populate the game levels, and will awake and try to attack you at the moment they see you. They can be of different levels, from 1 to 10:

Monster Lvl |              Name
          1 |        Homunculus
          2 |               Imp
          3 |      Lesser Demon
          4 |             Demon
          5 |     Greater Demon
          6 |     Lesser Balrog
          7 |            Balrog
          8 |    Greater Balrog
          9 |    Balrog captain
         10 |                 ?

The greater their level, the more they will have health points, and the more they will inflict damage.

They can move one square on each round. Balrogs, which are winged creatures, move differently than others (even you !), and can move and attack in the eight directions. Other weaker monsters only move and attack in the four directions (north, south, east and west).

If you manage to kill a monster, it will drop some mushrooms to the floor. If a monster manage to take such a mushroom on the floor:

  • if injured, it will eat it and be fully healed;
  • otherwise it will eat it and will gain a level, call another demon to help him or eat the mushroom with no other consequences, depending on the level monster and the dungeon deepness.

[edit] The weapons: basics

Weapons are of 4 different kinds : swords, axes, spears and warhammers. They can be of different quality : basic ones for training, or made of iron, steel, mithril, adamant or vorpal.

Every weapon, when used against a monster, provides the same basic damage, based on your level and the weapon quality.

Axes and warhammers are bigger weapons than swords and spears, and as such if you use them just after being hit, you will have a damage penalty, and the message: "You feel fuzzy while you use your weapon..." will be displayed.

[edit] The weapons: advanced

Every weapon has a special ability that you can use to multiply your strikes, causing devastating wounds if you are a true master of arms !

  • Sword charge

You can charge with swords to increase the damage you inflict. To do so, you need to move in one direction for several turns with your sword, then hit a monster in the same direction.

Sword charges, when succeeded, are indicated by the yellow blod message: "Sword charge #n!" where n is the charge amount.

  • Axe whirlwind

If you kill a monster with your axe, you will initiate a whirlwind attack, and attack every monster around you, the first at 2x damage, the second 4x, and so on.

Axe whirlwinds, when succeeded, are indicated by the yellow bold message: "Axe whirl #n!" where n is the damage multiplier.

  • Spear charge

If you kill a monster with a spear, you will charge in the same round on the monster killed position, and if there is a monster next in the same direction, you will attack it with double damage. If you kill the second monster, you will charge and attack with 4x damage, and so on until there are no more monsters aligned.

Spear charges, when succeeded, are indicated by the yellow bold message: "Spear charge #n!" where n is the damage multiplier.

  • Warhammer charge

When you hit a monster with your warhammer, there is a chance that you succeed a warhammer charge (based on monster level and you warhammer quality). If you do so, you will move one step ahead, and the monster will be pushed several steps backwards. If the monster hits something or somebody while being pushed back, it will be knocked for several rounds.

Warhammer charges, when succeeded, are indicated by the yellow bold message: "Warhammer charge #n!" where n is the number of cells the monster is pushed back.

[edit] Frenziness

[edit] Your mood

Your mood points are displayed on the upper-right corner of the screen. They are followed by the frenzy threshold and the berzerk threshold:

M 12/40/120
(12 mood points / frenzy threshold at 40 / berzerk threshold at 120)

Those mood points are affected by particular situations. You can gain mood points when:

  • you suffer from wounds
  • you kill a monster

And you loose mood points when:

  • you rest for a while
  • you drink a health potion
  • time passes

When your mood points reach the frenzy threshold, you reach the frenzy state. And if it reaches the berzerk threshold, you reach the berzerk state.

[edit] The frenzy state

When frenzy, you get damage bonuses with every weapon, and you can use axes and warhammers with no penalties.

[edit] The berzerk state

When berzerk, you get the advantages you can have when frenzy, with even more damage bonuses, but there is a price to pay: the thrust for blood overwhelm you, to the point that it's impossible for you to drink a health potion.

The only solution for you to leave this state is to calm down or rest after all the monsters around you are dead.

[edit] Player advancement

Every time you kill a monster, you gain as much experience points (XP) as the monster has health points.

You start your adventure at level 1, with zero XP. If you manage to kill enough monsters to have 30 XP, you will reach level 2 and your Health Points will increase from 10 to 15 HP.

Each time your XPs reach a new threshold, you will gain a new level and your HPs will increase accordingly.

When you gain a level, you are automatically healed from all your wounds.

[edit] Files

[edit] The 'moe.ini' file

The 'moe.ini' file is a text file containing parameters used by the game. Here is how it looks like by default:

record = True
speed = 500 

width = 40
name = Random
height = 40

dirs = {32: (0, 0), 273: (0, -1), 274: (0, 1), 275: (1, 0), 276: (-1, 0)}
fullscreen = False
tilesize = 12
screenheight = 600
music = True
screenwidth = 1024

dirs = {32: (0, 0), 258: (0, 1), 259: (0, -1), 260: (-1, 0), 261: (1, 0), 350: (0, 0)}
cols = 30 

If there is a problem with this file, just delete it and launch the game, a new 'moe.ini' file will be created with those default values.

[edit] The [Movie] section

  • record = True / False : if True, a keymovie file is saved when the game is finished (see 4.3 for details).
  • speed = 500 : when displaying a movie, speed of turns (in ms).

[edit] The [Game] section

  • width = 40 : the width of the dungeon. If changed, will generate a different dungeon, even with the same dungeon 'name'.
  • name = Moria : the dungeon name. For a given name, width and height, the same dungeon will always be created. If you change this name to 'random' (without the quotes), a random name will be given to the dungeon when a new game starts.
  • height = 40 : the width of the dungeon. If changed, will generate a different dungeon, even with the same dungeon 'name'.

[edit] The [Curses] section

  • dir = {} : a Python dictionary containing the Curses direction keys used in the game. You can change those values if you want to set other keys for moving.
  • cols = 30 : the width of the messages display area.

[edit] The [Pygame] section

  • dirs = {} : a Python dictionary containing the Pygame direction keys used in the game.
  • fullscreen = False : Change it 'True' to play the game fullscreen.
  • tilesize = 12 : the size of font tiles.
  • screenheight = 600 : The screen height.
  • music = True : Change it to 'False' if you don't want the music to be played.
  • screenwidth = 1024 : The screen width.

[edit] Savegames

After the first play, an 'moe.sav' file is created in the game folder to keep your progress. Launch again the game and it will continue where you previously stopped.

If you die, your score is stored in the savefile and a new game is initiated.

[edit] Keymovie files

If you die, a keymovie file is created in the 'movies' folder. You can play it with the command :

python moe-curses.py movies/keymovie_name.moe

To exit the keymovie, hit CTRL+Z.

[edit] Morgue files

If you die, a score is given and stored both in the savefile and in a morgue file. Each dungeon has its morgue file, so that you can compare your score in a dungeon with previous games.

Morgue files are stores in the 'morgue' folder.

[edit] Genesis of the game

This game has been created for the 7 day roguelike challenge:


The code was only one file: http://landsof.elderlore.com/files/moe/moe.py. I wanted it to be full GNU/GPL v2, so that it may be of some help for anyone interested.

I started developing it with simple needs in mind: I wanted to create a little roguelike around the new dungeon generator I had just created for Lands of Elderlore, my other roguelike. And I wanted to test how I could implement those simple features:

  • Permanent levels; well, not only permanent levels on your computer, but on every computer of every player! So that when you provide (automatically or by player input) a dungeon name, the same levels will always be created.

Python is a great language for this, and it is really easy to store dungeons in a dictionary and save games with the pickle module.

A common risk when creating permanent levels is to reduce the amount of space to explore for the player: once every level crawled, what can he do? So I decided to create two downing stairs for every level, each one leading to a different -and permanent- level.

There are 9 floors in Mines of Elderlore. That may not seem a lot, but with this 'two-stairs' design, you can have as much as 1 + 2 + 4 + 8 + 16 + 32 + 64 + 128 + 256 = 511 different floors!

Having permanent levels provides a great advantage: player can compare their scores. I did not have time to implement it yet, but I plan to provide an online display of every player scores on landsof.elderlore.com. By sending their keymovie files, not only players will be able to compete with each other, but when published online their movies will inspire other players and challenge them to perform better! Some kind of Massively Mutliplayer Offline Role Playing Game ;-).

  • Easy gameplay; roguelikes can have a steep learning curve for new comers, and to my point of view every effort to ease their first roguelike experiment should be sherished.

First idea is to display symbols with two ascii characters. So that the player can see at a glance what weapon he is wearing, what level is the monster in front of him, and so on. Simple and effective. And with fonts twice as high as large, symbols are displayed perfectly squared!

Then I tried to add weapon special attacks based on the player movements rather than additional keys or over complicated RPG skills. Charging is maybe the simplest example: by moving in the same direction during several rounds, you increase your 'charge' amount, and if you manage to hit a monster at the end, you will inflict increased damages.

I think this enhanced gameplay based on player movement can really be developped very far; you can count on me to investigate further on this !
