Squad formations and shooting

The units go into formation and shoot. For now there is only the line formation, but you can toggle the direction the line faces by pressing the direction keys. The units shoot at a steady rate, but stop shooting when you change directions, so you can’t just go back and forth to quickly shoot all directions. I might add a timer to prevent you from changing to rapidly, or I might leave it. Right now with the small number of units it kind of just feels like r-type :) Not that that’s a bad thing but it’s not quite what I was going for.

The units only move forward when they are facing to the right, so you can stop to fight things off and then set them marching forward.

Nothing to shoot yet, but that comes next. Then I find out how tough I can make it to force you to need to change your formation.
