That background was giving me motion sickness when you're in the rocket! I think a little less on the rotation would help a lot here. I also found it quite difficult to understand - I felt I needed more guidance as to how to make fuel for the rocket and which materials I required for that. Would love to have some sound in there as well - would be great to have audio feedback for the mining and for the crafting! I really like the idea you've got here though. Good job!
