Fun game :)
I agree that knowing how the stickers are going to be calculated would be nice (maybe a cheat sheet at the left side of the table that you can access at any moment? it's pretty empty there). Also when you hover over your hand's cards, a bubble with the card's original suit and number would be nice -- sometimes you run out of space to put stickers in and you forget what it was at first :sob:
I really really like it though !! I'm not nearly as good as making broken combos as some comments here but I enjoyed it, haha. Buen trabajo :)
