I have been playing this game since I rated it. It is quite challenging which makes it addictive. However, there are also some frustrations, which I hope you don't take offense. I would really want to play this game in a fulfilling manner since it's a really fun game.
There are objectives that seem impossible to achieve in just 9 turns. For example, I have 500+ wood and the objective requires 1300+ wood yet the only resources to gather wood from are limiting (e.g. Earn 0-3 wood, Earn 2 wood each turn you don't take a forest) Even if I acquire a forest which doubles the effect of the next forest, it doesn't feel enough to reach the objective.
I also don't feel the effect of upgrading the town. Instead of reducing the cost, perhaps increasing the number of turns would be more helpful (or every time you upgrade, the player can choose which would be beneficial for their current play: more turns, reduced cost, etc.)
I am not sure if there is an end game or if it is an infinite play until there is no escape from Zroth. Maybe once you have captured 100+ locations, you can add a mechanic which allows you to defeat Zroth. Perhaps this is actually possible now, but I won't know.. I am only able to take over 60+ resources then the objectives become harder to achieve.
My comment is quite long, but this is how I show my sincere admiration to this game. It is aesthetically beautiful and if you refine the game design, it would be one of my go-to cozy strategy games
