Enjoy the demo! This is the second version already and several updates will come in the coming months. I will work on new features and any bugs and visual quirks I find in the meantime:
New in this build:
-Fortify mechanic. A new mechanic that lets you convert existing Units into a Power/Health bonus for new Units;
-new menu image and layout;
-fixes to sound and Help menu's.
To be developed:
-Bonus cards: I'm considering guaranteed new common and uncommon cards handed out for each Enemy or Level defeated, to help completionists;
-Trophies;
-New Enemies.
