Thank you for your feedback!
Yeah, there isn't much to do except pick up the items spawning on the north of the map.
I just couldn't get my Resource Node script to connect to my items and drop pickups, so half of the stuff I was working on up to the end just didn't work (item interactions, equipping, harvesting and mining) :c So I had to release as is for now and I'm still working on it!
I love GDquest and I tried watching some Godotneers too during this time!
Since you're also using Godot, I also found Oops I Dev'd really helpful for my inventory scripts!
