The initial version, released on December 2, 2009, was more limited than any other edition of Minecraft ever released to the public, including the pre-classic version that is available from the Java Edition launcher. An update on December 4th changed the controls and added widescreen, more blocks, and the ability to place and destroy blocks.
The player can place and destroy blocks. The only block the player can place is grass, reminiscent of the very early builds of Minecraft internally called RubyDung that are available from the Minecraft launcher. Leaves do not decay.
The same 64×64×63 block world is generated every time the game is loaded. The only blocks in the game – air, grass block, dirt, stone, bricks, wood, and leaves – are scattered throughout the world. No mobs exist.
The initial build of the game only has one type of block, which uses a XOR fractal as a texture.
The player can move around using standard WASD controls, as well as jump using Space.
Left- and right-clicking controls are reversed from traditional Minecraft controls; left-click places blocks and right-click destroys them. Middle-click also places blocks weirdly enough. Moving the mouse turns the camera "smoothly," similar to pressing F8 in Java Edition, and cannot be changed in this version.
The camera acts differently to Minecraft's. The camera only moves when the player moves the cursor a considerably large distance away from the center of the game's viewport. Blocks in the world are selected by the cursor, rather than the center of the viewport.
The game lacks any sort of options menu or HUD.
The graphics appear pixelated as a result of the game rendering at a low resolution. Even when running at a higher resolution, the game does not scale the resolution properly and the noisy appearance is retained. Block textures are similar to those used in Classic, as Classic 0.30 (Creative) was the most recent version of Minecraft at the time. Most blocks appear noisier than their Minecraft counterparts, although some blocks, especially stone, are a lot different. The sky is black due to the lack of a skybox.
When hovering the cursor over a block, the outline of the block is thick and white, as opposed to Minecraft's thin gray block selection outline.
A comparison of Minecraft 4k's and Minecraft Classic's block textures.
The first version of the game has a single non-air block.
In the second version, block IDs are stored with four bits, resulting in 16 possible IDs. The majority of these are filled in by slightly differently textured dirt.
