Yoo bro, thank you a lot for your big and extremely constructive feedback!
First of all, I’ve gotta say you literally took the words right out of my mouth regarding using the adventurers' guild to defend the town. I'm designing this game with the vibe of not just playing a city-builder, but also "watching a fantasy anime" (just not an isekai/reincarnation one). And in anime, that's exactly what the adventurers' guilds do!
It’s a super interesting idea to give "Heroes" (as a general term for the MC, advisors, and unique characters) active abilities so they can personally defend the town from the likes of Mr. Skeleton.
Honestly, I’ve always loved how a critical bug or oversight can accidentally create a hilarious story, like your Mr. Skeleton wiping out 30 people on Main Street :D
As for the resource and production balance, it's a known issue and I'm currently working on it. Charcoal actually has some really weird bugs right now—sometimes it’s sitting in the warehouses in huge quantities, but the settlers still freeze to death anyway...
Long story short, I’m working hard on improvements and bug fixes, bro. Your feedback is absolutely phenomenal in how constructive it is. Thank you so much, I really appreciate it!
