War! A card game. (Beta release)

This is my first project in Godot, I wrote this while undergoing chemotherapy.
Game design is a wonderful way to focus and exercise your mind, if you find yourself locked inside for some reason.  

Any donation you make helps my morale and the development of this game and other projects.  I am a one person studio-  and a old dude in a world of young whippersnapper geniuses!

 After 35 years in other languages (Basic, QBasic, VB, Python, Gambas, HTML) and game engines (15 years in Gamemaker).   I released some projects for Linux in the past.  But mainly just made games for friends and family, and coded applications and websites for work.

I started playing with Godot when I when I started chemo, as well as Love2d and Defold.  (I am a huge 2d fan).  I chose Godot simply because I know Python.  But I am making games in Lua as well. Lua is an awesome high level language!  

Anyway this is 1 complete level of War.  You battle each other with cards.  It really is a test of the basic concept of the game.

Any feedback would be helpful, as this is very early release and your suggestions I am sure will lead to a better game.
