Overall I think this is a very cool concept, but the pace of the game is very fast and makes it hard to keep up with. Due to this, it makes it very hard to familiarize yourself with the cards. My first two playthroughs I was just selecting the cards with the highest number and was confused why I kept losing. I think starting the enemy off at a lower rate at which they place cards and then speed it up in relation to how low their health is would help a lot. The game is also very loud. I like that you added background music and sound effects, but it can be a little overwhelming how many sounds are playing at once. As far as the technical side goes, I didn't see any bugs that I could find, and the card system works very very well. I also like that cards will disappear as you've used them and the cards you can't use also disappear. The player feedback felt lacking despite all the sounds being played. In this aspect I wish I could say more as I am not very familiar with these types of games. Overall, I think your biggest issue would make the game start slower and speed up and this would make it a lot easier to start and add some interesting progression. This is a very good submission and I enjoyed it a lot once I understood it! Good work!
