Looks incredible and the gameplay is really fun! The vibes are really good, love the slight glow on things. I wish the pixel perfect camera wasn't as harsh, messes up a lot of the sprites. I think more feedback on the rarer ores would be an incentive the stay on a planet longer and dig deeper. Flying the spaceship was also quite fun. I think you have a solid foundation for something really fun. The jetpack also kind of trivializes a lot of the early digging and escaping, maybe should be an upgrade or be weaker.
It's interesting how yours and mine share a really similar core mechanic but is so different :)
