Thank you so much for the insight and kind words!
Yes, what you said is true. I wanted to put more content and make the game more realistic (like I only put ore nodes on the first 4 planets because the others are gas planets except Pluto.) and yeah I agree that the gas planets should not be able to be landed on.
I really do appreciate your suggestion and the fact that you see the direction I was going with the game. The mythological path seems like a very nice flavor, noted. I will be adding more content in the future!
