Bloody fantastic. Not just that it threw me right back into my youth thanks to the "Final Fantasy"-like soundtrack and because of the gorgeous pixel art, but also the gameplay is so well designed. I spent already two hours with it and I absolutely love it. It was fun to explore the different types of cards and to be in a dungeon, where not just the enemies, but the environment itself is quite hostile (I mean the acid drops and the spikes). Stunning work, mates. Gladly I wrote a praising article of your game and also uploaded a little gameplay video of it - may more players be driven to your Ludum Dare 41 entry! Keep it on, you're awesome game developers!
Best wishes,
Sebastian
