Hey, nice start to the game! I really like the vibe, art, and gameplay loop. I did notice that some levels didn't spawn enemies which worked out for easy XP, but it left me wanting more to do. I also noticed that some of the tutorial was little hard to follow. For some reason, when I went to play a card, it didn't seem to let me play one when I clicked the card. I'm not really sure how I got through it, I just started clicking around the screen until it let me get to the next screen. I'd love to see more cards, variety in enemies, and different level layouts. But I do think you have a really solid start to the game and it is going in a good direction. Good job!
