Great game, super well made and polished. I really enjoyed the twist at the end of each world where you have to select a few to bring with you. The game was very well crafted and almost entirely bug-free (lucky clover didn't seem to stack the way the text would imply?). The loads felt a little clunky (BIG load at the start and my game would freeze every time a new visual effect had to appear). But neither of those issues really hindered the game from feeling very complete and well-crafted. Kinda small but I was really impressed to see how much settings you took the time to include in a game jam game.
I actually ended up making a similar type of autobattler game, so it was really interesting to see where our designs diverged.
P.S. I gave Umblight a play while looking at last jam's submissions and really enjoyed the hidden information mechanics on the cards. Very clever stuff, looking forward to that full release eventually.
