Reminds me a bit of Minecraft but in 2D. Browser version is a bit buggy on Mac in Safari - I'm hoping Godot fixes this in 4.3 when that's released soon. Like the other commenters I would have liked a sort of play through tutorial maybe - perhaps you pick up existing resources initially, then forge, then move on to mining/killing etc.
Overall tho this game has a lot of depth for a week long jam!
