The visual style is top-notch, I love the originality and simplicity of the gameplay. I found the tutorial text to be more complex to understand than the battle system actually was, and I had some trouble with hitboxes when placing my cards, often having to drag 'n drop my card over five times for it to be played. Besides that, I had a lot of fun, nice sun/moon duality! I would definitely play a more fleshed out version, the suites could have each a special additional effect. Awesome work!
