The concept of the game is incredibly cool! At first, I had no idea what was happening or what I was supposed to do (and honestly, I never figured out what the 'Sacrific' card does). After a couple of rounds, I figured out most of the cards and managed to win.
The game is great! I'd love to see an endless mode and a smarter enemy card spawn system, so you could play for a high score instead of being timed. I really enjoyed playing it!
