I managed to get the simple 2D gameplay working but with a few hiccups that I will try to work on the weekend; such as the enemies not detecting each others collision and ending up at the same spot. I think the problem is that the update function keeps overwriting the collision system and sending the ships on the same spot.
I think the solution is ray casting collision, which I will look at.
Scripts I've done;
Bullets, collision with enemies, destroy enemies when hit
Enemies, following Player and destroying it when hit, speed up over time
Player movement, mouse pointer as aim, camera following player
