• Currently unobtainable without world editors.
• Not in the starting house chest.

Emerald ore^[a]

• Drops 1–3 emeralds.

Gear^[b]

• Can only be obtained by inventory editing and initially invisible in the inventory.^[4]
• A gear's sprite consists of two parts; the center rod and the animated gear itself.
• When hacked into the game, a gear can be placed anywhere, but would show nothing in its block space and would be 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 cannot be destroyed by mining a block that its gear sprite is shown on, because the placed gear is actually adjacent to that block.
  • If the block a gear sprite is shown on is 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 cannot be destroyed directly by the player; attempts to do so would phase through to the block behind it, much like water.
  • A placed gear can only be removed by explosions.
  • Later replaced by redstone dust.

• 1–3 are dropped from coal ore.

Controls

• Right-clicking on a stack picks up or puts down a single item.^[2]
• Left-clicking on a stack picks up or puts down the entire stack.^[2]
  • 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.^[5]

1 bug fixed

From Indev 0.31 20091231-2255

• Due to the removal of armor sprites from in-game play, it is no longer possible to grab the sprites out.

5 bugs reported

• Crafting menu does not open when pressing ^[6]
• Blocks and arrows each form separate stacks in the inventory^[8]
• Graphical glitch when game starts.^[2]
  • Clicking corrects it.
• Pressing a movement key at the same time as opening a chest causes that movement key to get "stuck".
• The game progressively degrades in performance.
