Honestly, this just feels like a timesink. Once in the 'game' bit, the only thing I can figure out what to do is to change my bet, keep trying to get more money, and go back to the menu. I can understand if you want to make a 100% free game that still gives the pleasures of gambling but come on, give me that casino feel. A way I think you should improve is work on the sound effects, I want a buzz when I gamble. Try make my total money flash whenever I win or have the sound of the cards being shuffle and dealt. The typo of "Sound" in the options is a little nitpicky to complain about but it's something I spotted.
