This is the fourth 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.

In the end on 2017 I understood, that to move forward with Steampunk Idle Spinner (which had 3 worlds and around 40 various machines), I had to rebuild the game core. This would provide a convenient way to design bizarre mad science machines, interactions between them and the player, resource transmission, production chains, etc.

To avoid breaking all that what was already working, I made the fourth world as a separate release. So, finally this branch of development has these useful features:

  • ability to drag machines all over the screen
  • system of LEGO-like "pins", to which the machines stick
  • detailed machines' properties, available on long-tap
  • statistics system, which helps me balance the game and you keep track on your earnings
  • bug-report system: the player can send me a small .png file where all the machines data is encoded, this helped greatly to define the troublesome points
  • as well as plenty ways for player's touch interaction, territory exploration, solid system for adding new entities and concepts.

Players continue giving new suggestions, which eventually appear in the game.
