I have a good suggestion for you, I know you are a BIGG fan of SpaceX. You have built your own versions of Falcon Heavy and Falcon 9. But what about Starship, I am not telling you to copy it just make a craft like that, like i have made my own rocket like starship.
And make it unique so it can not just travel to cylero but can also travel to other rocky planets like sergeaa, vulco and all moons.
