Pretty good concept and idea, it kept me hooked for a good while, unfortunately it got very repetitive, maybe you could make the player get different types of resources, and different upgrades to help him, like some drones and things like that. It reminded me A LOT of Dome Keeper, both have basically the same gameplay loop, mine for resources, get back to base, upgrade, and return, but on Dome Keeper's case you still need to defend your base, just like a tower defense, and I think you could go in that direction, or something similar with this game. Maybe you could defend your ship from space debris or asteroids, even aliens, you have a lot of options to choose from. The UI was Awesome, I loved it. I really liked you game!
