Timeline is a minimalistic management game simulating a network economy through space and time. It has been developed  with Unity for the GMTK game jam 2021. The theme of the jam was "joined together". Its gameplay rely on joining different kind of worker, ressources and locations together in a big economic network to produce more and more advanced techonologies. It proposes to illustrate how any product is the result of the joint labor of a multitude of people.

How to play

  • Drag the round anchor at the end of a wire on an empty place in the timeline to build a new location.
  • Drag the round anchor at the end of a wire on an existing location to link two locations and create a new ressource.
  • The anchor that has been placed can  be removed or moved only if no location depends on it.
  • The wire has limited size and the number of anchor that can be linked to a location is limited so be careful to not be stucked. If you are stucked, remove the last anchors you placed to unlock the situation.
  • Put the mouse cursor over a location to display the ressources the location produce and the ressources it can convert.


This game is inspired by the  woolen coat example written by Adam Smith in The Wealth of Nations :

The woolen-coat, for example… is the produce of the joint labor of a great multitude of workmen. The shepherd, the sorter of the wool, the wool-comber or carder, the dyer, the scribbler, the spinner, the weaver, the fuller, the dresser, with many others, must all join their different arts in order to complete even this homely production. How many merchants and carriers, besides, must have been employed in transporting the materials from some of those workmen to others who often live in a very distant part of the country! How much commerce and navigation in particular, how many ship-builders, sailors, sail-makers, rope-makers, must have been employed in order to bring together the different drugs made use of by the dyer, which often come from the remotest corners of the world! What a variety of labor too is necessary in order to produce the tools of the meanest of those workmen! To say nothing of such complicated machines as the ship of the sailor, the mill of the fuller, or even the loom of the weaver, let us consider only what a variety of labor is requisite in order to form that very simple machine, the shears with which the shepherd clips the wool. The miner, the builder of the furnace for smelting the ore, the feller of the timber, the burner of the charcoal to be made use of in the smeltinghouse, the brick-maker, the brick-layer, the workmen who attend the furnace, the mill-wright, the forger, the smith, must all of them join their different arts in order to produce them.

can you add an undo button because i have to restart the game every time i make a mistake


I loved playing! Is there an end or an Easter Egg after so many landings? I played through 8 landings but saw nothing. I would love to see a ver.2. Perhaps more difficult progression, like starting with 15 kids is critical to end game. Just shooting ideas. If you would rather not I would love to tinker with it.


moral of the story:child labour is the key to successful progress and space flight

Thank you for reporting the problem! Can I ask which browser you were using when it happens? I tested in chrome and firefox and it starts normally.

Love the game. There's only one thing I can say that makes this game a little hard to try and map out, the text.If there was an option to change the text to something easier to read this game would be perfect

I very enjoyed the game, it was very relaxing. The minimalistic artstyle was very good implemented and the lack of UI also adds to the feeling. The only thing I would change is the lenght of the game, I only got to the socond stage, I have no cloue if that was the last one. And I didin`t get what the game has to do with time lines, exept that it may seem like one.


Was hoping for causality between multiple timelines. Still, good concept and great execution. The drag-and-drop and scrolling UI is great, and great hover tooltips, though I personally didn't like the inefficiency of the UX. The same could be done and played much faster as a text-based puzzle much like any idle games out there. Didn't finish the game due to lack of patience.


lmao I made a cowpocalypse timeline 


Nice game. Has some issues with resources spawning below where you can see them, but other than that,... The NewGame+ animation needs to be faster or give some indication something is going on. 

I did keep playing until I got 5 space modules :D
