Great to see a card game in a game jam!
I agree that the UI is a bit confusing, but I did get the hang of it after a few tries and won. An in-game tutorial would have been great, but this being a game jam game I understand there's not much time for such things.
The best part of the game is the bluffing mechanic, which ties into the theme really well. It would definitely be fun to play with friends as a physical card game, almost like a more casual version of poker.
Awesome work!
