I really enjoyed this demo! I can definitely see how this could be an excellent short (short in this genre of idle/incremental anyway) polished little experience. I agree with the other commenter that the kinda puzzle-y aspect of this goes a long way. Expanding your influence into ruling larger lands (map size increases) with new resources / areas to explore / puzzles to solve, and so forth, are all things I personally would love in this game. The aesthetics are on point, too. Thanks for sharing your game! Really looking forward to updates!
(A little moving character would be cool, but if that does happen, I would love some sort of plot (even if minor/silly, depending on your preferences) as it adds a personal aspect imo.)
