Great tutorial!
Just one little update for Unity 5 users in regards to sorting the particle system. No need for a coding script to sort the layer. Go to your particle’s Inspector, expand “Renderer” and you should see the fields “Sorting Layer” and “Order in Layer” (close to the bottom). Select the sorting layer that you wish the particles to appear on. Ta Da! Your particles are sorted. Hope that helps someone. : )

Hi I am Using Unity 5.5 and Rigidbody2D does not have a method AddForce.
I get this error when I compile:

Type Unity.Engine component does not contain a definition of AddForce and no extension method AddForce.

Never mind after learning more about the Rid

After learning more about the Rigidbody2D I added the following and it works fine.

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class MouseController : MonoBehaviour {

public float jetpackForce = 75.0f;

private Rigidbody2D rb2d;

void Start () {
	rb2d = GetComponent<Rigidbody2D>();
}

void Update () {
	
}

void FixedUpdate () 
{
	bool jetpackActive = Input.GetButton("Fire1");

	if (jetpackActive)
	{
		rb2d.AddForce(new Vector2(0, jetpackForce));
	}
}

}

Regarding the mouse ,the Enable the Fixed Angle checkbox inside the Rigidbody 2D component is not supported, under Constrains check the Z box of the Freeze Rotation Constrains.

Fixing the Particle System Sorting Order for Unit 5 and up users.

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class ParticleSortingLayerFix : MonoBehaviour {
private ParticleSystemRenderer psr;

void Start () {
	psr = GetComponent<ParticleSystemRenderer> ();
	psr.sortingLayerName="Player";
	psr.sortingOrder = -1;
}


void Update () {
	
}

}
