Cube World is a voxel-based action role-playing game developed and published by Picroma for Microsoft Windows. Wolfram von Funck, the game's designer, began developing the game in June 2011, and was later joined by his wife, Sarah. An alpha version of the game was released in July 2013, but saw sparse updates and communication from von Funck, with many considering the game to be vaporware until he officially released it on September 30, 2019.
