=== Blocks ===
; [[File:Diamond Ore JE1 BE1.png|32px]] [[Diamond ore]]
* Not in Indev house block chest.
* Drops 1-3 diamonds.

; [[File:Block of Diamond JE1.png|32px]] [[Block of diamond]]
* Not in Indev house block chest.
* Drops itself.
* Currently unobtainable without world editors.

; [[File:Gear.png|32px]] [[Gear]]<ref group="note">Evidence of gear introduction in this version:
* The in-20100125-2 jar contains no gear textures.
* The in-20100129 jar does contain gear textures, which are dated January 26, 2010 1:13-1:15 UTC.
* Notch's January 26, 2010 1:36 UTC YouTube video displays functioning gears.
* This is evidence that functional gears were in any version released between January 26, 2010 1:15 UTC and January 29, 2010 14:53 UTC.
** ''That includes this version.''</ref>
* Could only be obtained by inventory editing and was initially invisible in the inventory.<ref>{{link|url=https://www.youtube.com/watch?v=M0888sLzYM4&t=2m12s|title=Minecraft particles, chests and spitting lava blobs. And a surprise.|author=[https://www.youtube.com/user/Nizzotch Nizzotch]}} January 26, 2010 1:36 UTC. Archived from [https://www.youtube.com/watch?v=V9H_ymjT-4E the original] on April 22, 2018.</ref> 
** At some point, this was changed to the animated version as seen when placed in the world.
* A gear's sprite consisted of two parts; the center rod and the animated gear itself.
* When hacked into the game, a gear could be placed anywhere, but would show nothing in its block space and was invisible unless horizontally adjacent to one or more blocks.
** The placed gear would then show a gear sprite on the near side of each of those blocks.
* A placed gear could not be destroyed by mining a block that its gear sprite was shown on, because the placed gear was actually adjacent to that block.
* If the block a gear sprite was shown on was destroyed, the adjacent placed gear would no longer show that sprite.
** Removing all blocks adjacent to a placed gear would remove all of its visible gear sprites, leaving the placed gear invisible.
* Placed gears could not be destroyed directly by the player; attempts to do so would phase through to the block behind it, much like [[water]].
** A placed gear could only be removed by explosions.
* Drops itself.

=== Items ===

** Crafting is not fully functional yet<ref>[[wordofnotch:359717446|Crafting on /indev/ now]] – The Word of Notch, January 29, 2010 15:04 UTC</ref>, with the only available recipe being an apple (in the top left-hand corner box) or more than one apple (one of them must be in the top left-hand corner box) to an arrow.
** Unlike with the inventory, the player can't move while crafting (just like versions newer than Java Edition Alpha v1.0.14).
** The maximum item stack size is only 1 in a box of the "Crafting" menu.

== Changes ==
=== Blocks ===
* Iron and gold ore now drop themselves.
* Coal ore drops 1-3 coal.

=== Items ===
; [[Control]]s
* Right-clicking on a stack picks up or puts down a single item.<ref name="WoN 0128 release" />
* Left-clicking on a stack picks up or puts down the entire stack.<ref name="WoN 0128 release" />
** It does not deposit more items than would create an item stack larger than the maximum stack size.
** The remainder remains hovering at the pointer.
* The player can no longer walk while having a chest open.
* Maximum item stack size changed from 99 to 50 for items in the inventory, and 100 for items inside chests.<ref name="release vid" />
; General
* Items now show as 3D voxel sprites.<ref name="WoN 0128 release" /><ref name="release vid" /><ref>[[wordofnotch:358356808|Published Image]] - The Word of Notch, January 28, 2010</ref>

=== World generation ===
; Indev house

=== HUD ===
* Fullscreen mode no longer affects GUI's, the hotbar or displayed text.
* Armor sprites no longer display in their respective slots even if the level is reloaded.

== Fixes ==
'''From Indev 20091231-2'''
* Due to the removal of armor sprites from in-game play, it is no longer possible to grab the sprites out. 

== Issues ==
* Graphical glitch when game starts.<ref name="WoN 0128 release" />
** Clicking corrects it.
* Pressing a movement key at the same time as opening a chest causes that movement key to get "stuck".
* It is possible to use more than one apple to craft an arrow. (See gameplay for some information).
