looks like a good first step! I wish there was a little pull action for opening the cards, dunno how hard that is to do though. I felt a bit overpowered by the second rent deadline so there was neither dread nor punishment. I also wish the tutorial showed you a round because I completely forgot about merging. also I think the effect of the card should be at the bottom or the text should be on the card like pokemon cards, I had to read a bit carefully.
hope this helps!!
(also if you need art I am an artist, though I'm a bit limited in resources right now. I am learning pixel art though.)
