This is the fifth, Underwater, world of Steampunk Idle Spinner series. The first version of idle game with spinning cogwheels was made in June 2017 during a 3-days gamejam. As the concept proved to be interesting for the players, the development continued. The development of the game is screencast and then published as 1:60 timelapse video. Some development phases are broadcast to the players as live videos and often the players' suggestions are implemented online.
