Shields & Guns now attach to the ship bodies. And ships can shoot!

Next steps:

<ul>
<li>Attach bodies to other bodies</li>
<li>Collision detection</li>
<li>Enemy ship generation</li>
<li>Cross-breeding & GA</li>
</ul>

It would be really great to get this all done today so I can focus on the ‘game’ aspects and polish tomorrow.
