Hello fellow developers!
Just finished building my Project Boost game in Unity! (Don’t worry, I’m sure I’ll get better LOL)
“After an incredible earthquake, farmer Hoggins is left stranded in the outhouse with no toilet paper! Help Farmer Hoggins find his missing TP, before another quake strikes!!” !
Controls:
SPACE = Thrust
A = Left
D = Right
Enjoy ! 
Here’s the code for the rocket ship. I did some searches outside the course to figure out how to program the lighting for the engines. I like the effect.
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.SceneManagement;
// fixed lighting bug from "Object Maps" tab on "Lighting"
public class Rocket2 : MonoBehaviour {
// [SerializeField] reveals the variable in the inspector
[SerializeField] float rotateMultiplier = 120f;
[SerializeField] float thrustMultiplier = 700f;
[SerializeField] float levelLoadTime = 1f;
[SerializeField] AudioClip mainEngine;
[SerializeField] AudioClip impact;
[SerializeField] AudioClip death;
[SerializeField] AudioClip success;
/* This will expose particle system to Inspector
* 1. SerializeField ParticleSystem
* 2. Add particle system Prefab to rocket game object
* 3. Drag child particle system game object to particle system in script
* 4. Code .Play() or .Stop() for particle system

Ha, brilliant! I love the concept and details.
Thanks for sharing the code too. 
Awh man, this is cool. The rocket sound and particle effects are pretty awesome
