Cool game. The cards are well drawn, the animations are cool (but sometimes they bug, for example, there is an empty space between the allied cards). The game lacks balance. At the beginning there is little mana, but at the end there is a lot of it and there are not enough cards. It is also strange that the opponent attacks the player and not his cards. And you can't attack the enemy directly, you need to destroy his cards first, it feels strange.
Also, for some reason, there are two exe files in the archive :D. If anything, run "Call of the Cards".
