Thanks for the feedback, Itch.io or unity, one of the two, wouldn't load the game unless it was a development build, I had a plan to let you stumble upon new worlds to colonize and that be your second chance if your world is close to or is dead, but I didn't have time to implement.
My stand in was for you to repair the infrastructure or shields of Earth by killing enough enemies. Anyway thanks for the feedback, I really appreciate it!
