This is a really well-crafted game. Great job on the music and sounds. The high-pass filter applied to the music on the new card select between rounds is one of many details that gives this game a great feel for me. The card game is fun and a great concept once you get the hang of it. The tutorial does a good job of explaining how things work.
This is a very strong submission and I hope more people see it. Maybe uploading a browser version will help. Good luck and congrats on the submission!
