Just jotted down my thoughts as I played:

• need some ui enhancements regarding buying/selling
• picking cotton needs to be easier
• villagers have difficulty looking for resources sometimes (I'd be right next to a tree, tell my villager to gather wood, and he'd think there wasn't any nearby)
• typography - you're using a display font for everything, pair up a display font with another font that's easier to read for better legibility
• need a panel for town statistics - job allocation, current number of beds (max pop), current number of population.
• minimap would be useful to keep track of villagers, villager routes, and other bases
• walls play a sound when hit, is a damage system for walls planned? if there's going to be wall destruction, then an easy way to visualize wall hp is essential.
• doors
• it's weird to me that M changes the material for building materials. Usually M would be minimap as a hotkey. It's also weird how it's always visible in the UI, I'd suggest making it only visible when building because i dont see a reason you need that information otherwise.
• a job and equip system for dedicated mercenaries using swords/shield/2h/crossbows would probably be more convenient for the player than it being an order in the order system (F5-F7)
• I wanna be able to press I to see an expanded inventory, and be able to equip weapons and armor from that same inventory (like minecraft, terraria, most other survival games)
• materials being of different rarities doesn't make a lot of sense and seems like it would just clutter inventories when gathering materials etc. I'd much rather see wood and metal just be considered common and the products you make out of them (shields, weapons) have a rarity. Additionally, if you want resources to have rarities then the most common ones would be common (stone, wood), then rarer ones would have a higher tier (iron, tin, etc.). It just makes no sense for everything to have a rarity. Why do I need legendary wood?
• animation for running and transitions between running and not running should feel smoother and tighter. right now it's kinda janky.
• not sure if theres a way to undo a construction, but if there isn't, there should.

Overall, the game looks to be on the right track. It has a lot of potential to be a fun PVPVE game, Right now it has a character aesthetic that reminds me a little of the Sims, it's a little cartoony which isn't a bad thing. It could work in your favour to set itself apart from other games. If you're going to shoot for something like this, you'd want to make sure all the other art assets are also in line with the aesthetic (right now, terrain, object design, ui, and color grading could use some visual tweaks). So things like the main menu, the terrain, the furniture, etc. All need to feel like they're part of the same world. I'd just straight up take notes from how games like fortnite, the sims, and other similar games handle their assets and graphic design. (perhaps look at the sims medieval for UI and texture inspiration https://pbs.twimg.com/media/ESVtLMRXkAIGRIO.jpg)
