Icarus: Movement + Shooting

My first goal in this project was to get the movement working over anything else. So after getting a dummy ship Malakai made I started to work getting it to move.

I attached three circles as child objects to the ship to act as reticles, as I need a clear view of where the ship is pointing and it helps give a sense of distance.

Movement code (ShipMovement):

using UnityEngine;
using System.Collections;

public class ShipMovement : MonoBehaviour 
{
	public float movementSpeed = 20.0f;
	public int yAxisMovSpeed = 1; 
	

	void Update () 
	{
		float horizontal = Input.GetAxis ("Horizontal");
		float vertical =  Input.GetAxis("Vertical");

		Vector3 direction = new Vector3(horizontal,yAxisMovSpeed*vertical,0);
		Vector3 finalDirection = new Vector3(horizontal,yAxisMovSpeed*vertical,1.0f);

		transform.position += direction*movementSpeed*Time.deltaTime;

		transform.rotation = Quaternion.RotateTowards (transform.rotation, Quaternion.LookRotation (finalDirection), Mathf.Deg2Rad * 50.0f);	
	}
}

I may need to rethink the movement algorithm as there is a finite distance the player can travel before reaching the end of the plane.

I also would like to layer the plane with transparency to create the illusion of parallax.

I was also able to create movement by instantiating a prefab and applying a force to it.

Forward shoot script (ShootForward):

using UnityEngine;
using System.Collections;

public class ShootForward : MonoBehaviour 
{
	public Rigidbody bullet;
	public float velocity = 10.0f;
	
	// Update is called once per frame
	void Update () 
	{
		if(Input.GetButtonDown("Fire1")) 
		{
			Rigidbody newBullet = Instantiate(bullet,transform.position,transform.rotation) as Rigidbody;
			newBullet.AddForce(transform.forward*velocity,ForceMode.VelocityChange);
		}
	}
}
