First of all, I would like to congratulate you guys on the game. It's really well done and cool.
I found it a bit difficult to understand how to make materials at the beginning, and even after figuring out how to make some materials, I felt the lack of a recipe book or something I could consult to better understand how to produce the recipes.
The feeling of discovery is amazing, and I think this idea has a lot of potential to become a strategy and planning game that I would definitely spend countless hours playing and optimizing to perfection.
By the way, setting up an infinite spear production line is quite OP in the early game and gave me a breather to try to figure out how to make other items.
Congrats guys!
