Hey there! Thank you for the awesome feedback! I'm glad you're enjoying the game so far.
Of course you can make suggestions, it will help me make the game better!
Regarding your points:
Walls & Raids: Yeah, walls durability is a my bad, will fix it. Actually, I’m planning to rethink the raid mechanic entirely. I'm considering something similar to Factorio, where a crowd of skeletons will first gather in the corrupted biome before launching the actual raid on your settlement.
Adventurer parties: The single-party limit is actually an intentional design choice for now. The Main Character is the key member of these expeditions, and im planning specific events and scenes tied to them (for example, when finding Astarta). It wouldn't make sense for these to trigger without the MC present. However, im thinking about how i can expand or adapt this mechanic in the future.
Workforce/Logging: This definitely sounds like a no free workers or priority bug. Thanks for reporting, i'll investigate this.
Closing gates is a great idea.
About idicators, will think about it, maybe some building should provide indicator... Like a observation tower or smth
