I was confused at first but I was hooked - This is a really cool game where you have to think critically to succeed and I love a thinking challenge or two. What also makes this game is the pressure to call bluff on your opponent since making bets too high is bound to fail you.
I have no issues with this entry whatsoever - I would only expand on on it. Maybe some more artistic elements like a backround pattern or anything to make the visuals feel more complete. The artstyle itself is still very strong thanks to its simplicity one way or another.
Eitherway, this is still a very polished entry
Great job!
