Rd-0.1.0a

◄rd-0.0.4a | rd-0.1.1a► 
rd-0.1.0a is a pre-alpha version of RubyDung released on June 8th, 2009. It is the first version of the late pre-alpha versions or officially known as the first of the pre-alpha 0.1 versions. It almost entirely overhauls all the aspects of the game, including gamemodes. 
Fortress mode is no longer a placeholder and has unique features. Like Dwarf Fortress, you are given 7 dwarves upon starting a new game. The dwarves are identical in appearance to the ones from previous version however seem to have tweaked AI. They still randomly wander however they will not walk as far as they once did. You can fly around to view the world similar to Minecraft's creative mode. Isometric view mode is still a feature and can be toggled by pressing the V key as before. You cannot interact with the world yourself anymore, but there is now a new gameplay mechanic where you can select a dwarve, and select from a menu that appears upon selecting one. There are 3 options: "Move", "Collect", and "Build". If Moving is selected, the block the player's mouse is hovering over is outlined. Any block can be selected and upon clicking on one, the dwarf will walk to that block if possible.
If Collect is selected, the selection process is the same, however upon clicking the block the dwarf will walk to any spot of a 3x3x3 block radius around the block and mine it. The block will be added to the dwarf's inventory.
If Build is selected, a GUI of the dwarf's inventory opens. After an item to place is selected, you are able to click on any given accessible space to place the block on. The dwarf will proceed to walk over to the area and place the block. If the dwarf has nothing in it's inventory, it must first collect something to place in order to use this function.
This system was tedious and could take hours to build simple things in Fortress mode. There were many complaints from the RubyDung forums over how difficult it was to manage dwarves in Fortress mode, and in response Notch said that it is still incomplete and will be improved in future updates.
Legends mode was barely changed. The slight tweak was that you could noclip through any block to view the world underground. It was almost exactly like Minecraft's spectator mode.
Adventurer mode become more functional and fleshed out. You could no longer collect water, and now had a healthbar of 100 HP. You could not drown or get attacked by anything. The only thing that can damage you is fall damage, which works like this:
The minimal height to take fall damage is from 4 blocks up. It takes away 5 HP.
For amounts higher than 4 blocks, 1 block = another 5 HP taken.
Example below:
* 5 blocks: 10 HP
* 6 blocks: 15 HP
* 7 blocks: 20 HP
* 10 blocks: 35 HP
* 20 blocks: 70 HP
* 26 blocks: 100 HP (death)
* etc, etc
You also have an inventory similar to Minecraft. By popular demand, storage is now more efficient and instead of a single block per slot, you could now stack up to 10 blocks in one slot.
Another minor addition is that trees returned to the game. Instead of going to all the trouble to make a new model for trees, they were instead made of regular blocks by popular demand of the community. They were practically identical to Minecraft trees and no longer glitched or crashed the game.
