An interesting and fun mix of a card and a board game. The core gameplay made me think a little bit of the battles in Etherlords, which I used to play when I was a kid. I also liked the little details, like the animation of the End Turn button, or the animation of a card being played. I wish it was a bit easier to tell which team units are on, especially the round ones :)
Unfortunately, I tried a few games and I wasn't able to finish any of them. Here's the error I saw in the console:
Uncaught TypeError: Cannot read property 'length' of undefined
at Soldier.endTurn (cards.js:63)
at Game.endTurn (game.js:223)
at Game.<anonymous> (opponent.js:78)
Overall, I'm impressed by the mechanics and the variety of cards. Well done!
