Excellent work here. I like that you made the game more about finding the cheater than "just another poker game" - very creative. First thing I did was randomly shoot someone lol.
I think the score calculations might be bugged? (unless I don't know Texas Holdem and the house is supposed to win?) but I got striked when I am pretty sure i was right. Anyway, I see that there are the hand rankings in the game, and you need the player to focus more than just the cards that are being marked to make it challenging, but I wonder if players who are not poker-savvy might get turned away?
This is a very difficult memory game. The only way I actually won was by relying on my photographic memory (taking screenshots)
Excellent work on the pixel art and the music too.
