First end-to-end project - All has been lost!

Defend against waves of incoming missiles. 
A tribute to Missile Command.

I've dabbled with game engines in the past but have never created anything that got past the "playing around" stage so this project is an attempt to create my first end-to-end (actually playable to some degree) game.

I chose missile command as my template as it is relatively simple, fun, but has opportunities to add some of my own ideas and personality into. 

I started looking into Godot about 2 weeks ago so the implementation is horrific. However having this focused goal did help overcome my instinct to perfect things. 

Feedback is welcome, but at this point I'm calling it complete and moving on to the next project.
