Hey, I think I found a bug.
I'm running the Windows version of the game on Windows 7 and while playing, when I click on a weapon card, instead of adding to my total attack, the value of the card replaces my current attack.
So if I have an attack of 10, and I click on a weapon card of a value 8, instead of getting a final attack stat of 18, I get a final attack value of 8.
It makes it hard to get past the second stage.
But otherwise, this is a very cool idea for a game. It could definitely become addictive.
