Cave game tech test[2] is the name of a video released by Notch on May 13, 2009. While the version shown was never publicly available to play, it was developed from May 10, 2009,[3] and showcased on May 13, 2009. It is the first known version of Minecraft, or Cave Game, as it was referred to in this time period.

Development[edit]

The Cave Game code was edited multiple times during the time it was developed. Here is a list of all known edits to the code:

  • May 10, 2009: Game first developed.
  • May 12, 2009: Fixed a performance issue.[4]
  • May 13, 2009 (17:41 UTC): Notch made it only update two chunks per frame.[5] The game generates blank chunks and the FPS is inaccurate.
  • May 13, 2009 (17:48 UTC): Game now runs smoother.[6]
  • May 13, 2009 (17:51 UTC): Chunks have been changed from 8×8×8 to 16×16, and chunks near the player will load first.[7] This was the build that Notch showcased on his YouTube channel.
