I see a lot of people comenting about the suits of the cards being confusing. They are the spanish deck suits, with the design in the cards being the ace of each suit on the original deck. Please do not change this, i loved seeing the spanish deck in the game when i opened the game.
I agree with the comments saying that there should be a textbox or label with info about the card that appears when you hover the mouse over it, with info like the suit, the number on the card and the stickers it has. It becomes hard to see the info when you have a lot of stickers
Also, the game felt too easy, i think that the latest rivals had not enough stickers on its cards and also that always choosing first is too much powerful.
I loved the game and seeing the spanish deck cards brought back a lot of memories. I hope you get succesful with the game
