Cube World is an open world role-playing video game in development by Picroma for Microsoft Windows. Wolfram von Funck began developing the game in June 2011, and was later joined by his wife Sarah von Funck. An early alpha version of the game was released on July 2, 2013. However, as of July 2015, the game is unavailable for purchase and has not received any updates since July 23, 2013. A significant lack of communication by the developer about the game's current development has fueled speculation about its future.
