Nicely polished but a little same-y, from the comments, maybe I was doing it wrong or just bad at the game. Shoot the asteroids, sell the ore, upgrade the cargo, rinse and repeat until no more, ore, upgrade shields, shoot the bad guys, die, ooh better ship. Nothing left here, went to the next world - no space station, fill the cargo hold back to the warp gate, back to the previous world to sell up.
I had my shields up to 120 and still died on world 3, by the time I could see the enemy they were on top of me - all a bit too close quarters for space combat IMO. Then I died again and was in the same ship but without the upgrades. That was demotivating TBH.
