The game is a bit problematic for someone who does not know how to play poker like me xD I mean, I saw the rules panel (thanks) but font size was too small for understanding eg. "oh, these on "pair" are the same number" :-P
Also, it felt a bit counterintuitive to me to drag and drop for placing the cards in the hand, but not for placing them on the table. I was trying to drop them on the table until I realized that it was done by clicking.
Lastly, are the dungeons fully random? On the first one I got an enemy with a 83, which was pretty hard to beat.
Nice game though, congrats!
