Played the easy mode, as I am not so familiar with this game. But I got quickly into it. Just take a short break to give you the great feedback your game deserves. I am commenting here, as you ask - but will leave a rating as well.
sound effects (not music) - good! the card shuffle and coin toss sounds fit very well. you created them yourself? the music is also a great choice - fits perfectly.
animations: also good. the transitions are lightning fast - as they should be. most transitions are too slow, but not yours. good job with that!
page presentation (how much were you interested from game cover, page, screenshots, etc): the game page itself could need some work. it's one of my passions to create good game pages for our Jam games, so i think i know one or two things about it (even created a collection, can you access it? https://itch.io/c/2003597/game-page-inspiration). try to make it big and inviting. the screenshots are definetely raising interest, and so does the logo.
And now - next poker round! :-D
