Thank you very much for the review. As for the orbiting planets, we made use Unity's transform.RotateAround() methods that basically rotates a gameobject around the Vector3. For the gameplay part, you need to launch the probe by clicking on the screen so that it hits or passes through a planet while it is traversing. When it the probe hits the planet the astronaut takes the position of the planet while dodging the incoming astroid. Again thank you very much, so glad you did the review.
