Thank you so much for all the kind words and detailed feedback. I truly appreciate it.
I'm glad to see that so many of the things you suggested were ideas that I didn't have time to get around to. I ended up not having enough time for balancing the card distribution other than "pick 3 cards randomly from all cards to offer" which obviously introduces a wild amount of variance. And that idea might have even been a little more acceptable had I gotten around to cards with abilities!
I like the dual-element suggestion; that hadn't made it onto my brainstorming list!
And to your final point - yes, I absolutely agree about it not feeling like there's a lot of room for skill or expression. Hopefully it will feel better after updates to card distribution, finer encounter tuning, and a dynamic decklist during battle that helps you better understand what's left to be played.
My plan was always to take whatever I made for this jam and develop it for a full android release just to get the practice of selfpublishing, so I expect I will be able to achieve all this!
Thank you again so much for the feedback. Truly appreciated. Jam on!
