Super helpful feedback! I'll lower the requirement for level 4 ranking up and increase smelter upgrades effectiveness. What are your overall thoughts on the game? Did you enjoy yourself?
I liked it. I think it needed more depth, like more kinds of ores, but I suspect that's already planned. It would be nice to be able to upgrade digging distance and jumping height. More jump height would make it safer to mine without having to worry about not being able to get back. By the end it feels like you can't even dig up because the explosions keep bringing you deeper.
