I have a few issues regarding planets
1. Saturn looks strange with no rings.
2. Why no Venus, Neptune and Uranus?
3 Doesn't twin moon mean there should be at least two moons? Two among them being somewhat identical?
And Lastly Shouldn't tidally locked planets not rotate? Tidally locked means one side is always facing the star, and since in the game the planets don't spin around the star they probably shouldn't rotate either.
