Fantastic!
I love the idea. There are so many crafting surival games out there, it's hard to do something new. Here's something new! And it's on theme!
The implementation is fantastic. I can see where it'd go with more time, but it's already a lot of fun. I hope you keep adding to it.
The music is soothing and a good choice.
The only note I've got is that I found acquiring wood to be really exhausting. Everything needed wood, and the vehicle frequently wandered away from any trees. And I hope turrets or something to automate dealing with goblins shows up in the tech tree at some point.
