It features music by Daniel "C418" Rosenfeld and paintings by Kristoffer Zetterstrand. Initially released as what is now known as Minecraft Classic on May 17, 2009, the game was released as Minecraft 1.0 on November 18, 2011. Since its release,Minecraft has expanded to mobile devices and consoles.
Minecraft focuses on allowing the player to explore, interact with, and modify a dynamically-generated map made of one-cubic-meter-sizedblocks. In addition to blocks, the environment features plants, mobs, and items. Some activities in the game include mining for ore, fighting hostile mobs, and crafting new blocks and tools by gathering various resources found in the game. The game's open-ended model allows players to create structures, creations and artwork on various multiplayer servers or their own single player maps. Other features includeredstone circuits for logic computations and remote actions, minecarts and tracks, and a mysterious underworld called the Nether. Ultimately, the completely optional goal of the game is to travel to an alternate dimension called the End, and defeat the Ender Dragon
