Great game!
Suggestions:
1) Have a research option that makes the individuals more efficient, thus increasing their mining/researching/healing capabilities
2) I understand the realism of the gravity assists, but the rocket does not need to slow down to zero speed
3) The further the rocket ventures, the more that the satellites should be worth. Or, there could be more of them.
4) After a certain distance, set up a tier system where coins can also be collected from the rocks. The further you go, the more the rocks are worth.
5) Mining is worth virtually nothing, so setting up an option where resources mined can be converted to coins. I have 10,000+ mined resources worth virtually nothing.
Hey, Goodcoolman. That isn't even a little true. Carbon Dioxide can exist without oxygen. Realistically, the entire atmosphere would be full of carbon dioxide after a large scale explosion.
