Good job with the game. It was a fun time to play and the art was very well done. Mechanically, I found it easy to understand but it had enough depth and strategy to keep it fun and interesting to play. I would really want to try out a multiplayer version a group of other players since it seems like it would be very fun.
I do feel the game is lacking a bit in the player feedback department and would benefit from things like sound effects for winning/losing/going neutral a bet and for when you play cards. I feel like the ui element for how much the pot has is placed such that it makes it seem like its a resource you personally have. I also feel like it would be smoother to have the "I think it will/will not fall" as two separate buttons and make it so the round just starts when you select one. Lastly, when you win the game doesn't actually end and it allows you to repeatedly play cards.
Overall a very solid entry and it would be cool to see it developed even further.
