I take it civilization level 8 is the highest? It was fun beating it, albeit a bit of luck is needed at the start of the late difficulty levels to get up and running. Definitely a fun take on the old fog of war idea.
Yes, 8 is the highest dificulty I added for the jam, at that point it will keep generating new puzzles on that setting.
Thanks for taking the time to play my game, I'm glad you enjoyed it
