Pretty cool game Oistar! The dealer is genuinely on some powerball lottery winning levels with how often I was hitting blanks on him. Unbelievable luck aside, this is a good submission.
The audio and visuals are very resourceful. There's not a lot of them, but they're used extremely well. I think the ONLY thing you might of been missing is some sort of background/ambient noise or music. I think a campfire noise or some sort fire in the background would help set the mood very well.
I think the dealers AI could also be changed. I only saw him look at cards and he didn't appear to do any other actions but maybe that's intentional design or just luck. Also its funny how the dealer says "I got lucky" when bro went for a 1/6 shot and missed.
Overall I like this one, not only is the gameplay unique and fits with the theme well, but you designed it to have a very cool atmosphere.
