You music is a bop! And the aesthetic of the game is very appealing, those floating head guards freaked me out!
It seems like you already know what needs to be fixed here: gathering materials is simply too slow, movement in town is too slow, and some inventory bugs. For what it's worth I couldn't build anything after the campfire because I couldn't find more books.
The interactive tutorialization of mechanics is well done. I think you also have an interesting idea on your hands. I think it would be very cool to play a game where you have to resource gather in camp, improve my character(s), and looting for other items at night in a high-risk-high-reward environment.
In my opinion, I think gating resources behind improving your character, with items, books, or whatever else, is fantastic. And that you can find the upgrades you need in the city, or another area. It would have been cool to see myself grow, improve, and move on.
Keep making games! I would love to see this idea expanded and improved.
