Cave game tech test

Cave game tech test [1] or Cave Game tech demo[2] is the earliest publicized unreleased version of what would become Minecraft. It was made on May 13, 2009, between roughly 16:48[3] and 16:55 UTC.[4] A video of the game at this time was recorded by Notch sometime between 17:00 and 17:14 UTC, and uploaded at 17:36 on May 13.[5] It is the earliest known version of Minecraft, or what was then known as Cave Game, to have been recorded.

Development of the game started around May 10[6] or 11[7] to May 12 at the latest,[8] and continued up to May 13, 2009, adding the features that would be later seen in the Cave game tech test video.
