That's a really cool idea, I vaguely knew the city Aachen from playing as German on Civilization games but didn't know the cathedral folklore. I would certainly give a try to a full version of the game.
Also as already said in other comments, crafting a real-time strategy game is no joke, especially for a game jam. You guys did a good job implementing the base mechanics.
Regarding the time management issues in the team, it is unfortunately very common and one of the reasons why I always do game jams alone hehe. Its easier. Still, good job, congrats on the entry folks 🥳
