Had a great time with this on stream and came back today to finish the boss! I don't know why I didn't hit continue on stream and have a second run at the boss. I think I just assumed I had to start over. Love the balance, the different card interactions and the surprise with the boss at the end. It's crazy, because this round was all about making a boss fight, but I was so engrossed in the game I forgot all about it, so it came as a surprising delight! Excellent work.
