Java Edition Alpha

Alpha is the fourth phase in the development cycle of Minecraft, replacing Infdev. There was only one type of game mode playable in this version, which was Survival.

During the Alpha phase, Minecraft was updated very frequently due to Notch working full-time on Minecraft since 29th May 2010 and having a small company made later. Bug fixes and tweaks could happen throughout the week, appearing on the game's development blog, with major additions and changes appearing in 'Seecret' Friday updates, leaving the game's players to discover the included new features.

On 11th December 2010, Notch announced that the game would enter the Beta stage of development on 20th December, at which point the price would increase to €14.95.
