Development
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.
 * May 13, 2009 (17:41 UTC): Notch made it only update two chunks per frame. The game generates blank chunks and the FPS is inaccurate.
 * May 13, 2009 (17:48 UTC): Game now runs smoother.
 * 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. This was the build that Notch showcased on his YouTube channel.
