I made it to 36 cards, solid handle on the gameplay, just working my way through. Went to check out Node Stream — and that's how I discovered there's no saved game. I suppose the cards win this round. Okay, seriously though — it's a super neat concept! I like the nuance to the card duels, having to tactically sacrifice cards to see what an opponent has, and swapping cards that you know you can win back, etc. It's neat! Well done.
