I was trying to do a poker variant for my jam entry, and I didn't even finish the hand evaluation part. I'm impressed. My feedback:
Negative:
the winnings should be higher than the loss fee. Your odds with AA against 3 hands is around 64%. I'd say payout should be 4x the buyin. As a poker player who likes mindless poker games I lost interest as soon as I realized how bad the odds are. Also, your buyin should be subtracted as soon as you deal.
Positive: I really dug the use of assets, the animations and the sound.
Good job.
