Loved this early access startup. I am sure that you have already realised that the colony can only grow so big before it automatically collapses. The reason I believe is because porters need to travel further and further as the the colony expands. This means that an exponential increase in porters is needed whilst the size of the only colony increases linearly. This problem finally causes a necessary good like food to pile up where it is made, but not be transferred to a storeroom, therefore the colony starts starving.
For the game to grow further, a solution like a grand storeroom could be introduced. The grand storeroom would require a goods elevator or passage with a store room node at either end. These nodes could then be incorporated into the porter's logic effectively dividing the colony into two or more separate portage zones and so solve the initial problem above.
I would also love to see some new features like guard posts, barracks, natural caves and guest quarters for visiting dignitaries. And a move feature that allows you move a room without the need to dismiss a worker would useful for grander designs. And one last question, where does the food for the pigs come from?
Since I didn't pay for the game, consider this my way of saying thank you.
