It's nice to someone create a card game in an a week long jam, cause they can be difficult. There are some little changes you could of made just to make this game so much easier to understand:
- Increase card size (espeically in full screen mode), I would of made this entire game inside of Unity's canvas.
- Changed button interactable depending on game state.
- Adding in little pauses when an action takes place or turn ends with a short animation
- Putting the game state at the top of the screen in bigger letter rather than off to the side.
