Galaxy Shooter.1

This is an updated version of Galaxy Shooter.0. A very fun project I am starting off with at GameDevHQ!

- The laser no longer hits Enemy collider2d so now only one explosion once the enemy is destroyed 

- You can no longer be hit by the enemy after it was destroyed. Before-after the enemy was destroyed you could still get hit due to the collider2d not being destroyed. 

- Fixed with Destroy(GetComponent()); in the Enemy.cs

- Enemies now fire a laser every 3-7 seconds

- Enemy speed slower because they now fire lasers as well every so often

- The enemy has 2 lasers both can cause damage and can take off two life points if both lasers hit

- Added more stars (blue) in the background
