This game is like a simpler version of hearthstone, and it is really fun and easy to pick up. To make a card game, I think the most challenging part would be the AI for the opponents. I think you guys did a great job to make the AI smart enough to play against the player, and I am sure that you guys have spent so much time on that. You can unlock new cards for beating certain levels, and this rewarding mechanism is similar to the famous game, "Plants vs. Zombies". Overall, I like the Art Work, sound effects, and it is pretty cool of seeing someone actually built a card game at the end of this semester. Good Job, guys!
