The ui and explanation were super clear. I understood it after 1 attempt. I think the shuffling speed increased a little too quickly. Maybe try adding more cards before adding more speed. It was fun and definitely replayable. I think it could benefit from having a specific card you look for each time, rather than choosing one more as a narrative element. Otherwise, a fun little arcade game :)

the game is beautifull , i enjey ed have the second best score all time :) . 
i guess its mostly luck after " or 4 level it's very difficult to follow and with the speed i am getting a bit deezy :) . i would suggest to put more brightness one card that we choose ( just to say something , it's really not big problem) .
funny and beautifull game .
