The Longing

The Longing is an indie point-and-click adventure idle video game, developed by Studio Seufz. Initially released for Microsoft Windows, macOS, and Linux on March 5, 2020, and later for Nintendo Switch on April 14, 2021, the game follows a creature called a Shade, who waits 400 days to awaken a sleeping king. During this wait, the Shade must find ways to pass the time. The game is notable in that the in-game four hundred days pass in real-time, regardless of whether or not the player opens the game. The plot of the game is based on the legend of Kyffhäuser.
