This is a fun game with great presentation! The overall direction is very cohesive, and the art and sound are great. There's a bit lacking in variety of content, but the core idea here is original and a lot of fun. The controls were very clear, and the objectives started to stack up and become more complex which was a great bit of variety that added depth to the gameplay.
My last piece of constructive criticism was that the battles felt a little flat. I couldn't read my cards after I had collected a few, and I think a little bit of feedback after playing an action could go a long way to improving the fights.
Overall, this is a great submission! Awesome work!
