I don't know if I am missing something haha but I can't build anything, I have no resources. I like the idea, and the music is cute.

You can interact with trees and rocks if you use the interaction button (LMB) by doing this you can collect resources . When you have enough resources you can build different structures. I was going to inplement some kind of tutorial system to the game but unfortunately didn't have enough time to do that during the game jam :)
