The scale part : going from a world view to a village view to a human cells view. As the game goes on, we scale down to the very smallest parts of a human being. And all of the scaling has a big influence on the larger parts of existence (village and island).
The built part : the deckbuilding, the accumulation of resources and the drawing of a map to return to the Queen.
I hope you understand the theme a little better, now.
I have to agree, though, it can be hard to link the Jam prompt with the game without explanations.
Thanks for playing and leaving a comment. I'll try your game after posting this answer.
