I think that the difficulty is a bit too easy. The only thing keeping me from beating the last level in one go, is my fuel capacity. I would suggest adding more parts, and please add a resource converter. I have nearly 300 stars, and there were many times when I wish I could have turned my stars into asteroids. Lastly, I have a question. What are the gears? Is it just a filler for when you mine out the galaxy?
