Hi, thank you for playing and for your feedback!
- I opted for an XP currency to better balance the game early on but yes I definitively see your point :) There is an upgrade that requires money, I might add more that requires money is the future.
- About the buttons, are you talking about the "hit/stand/..." or the "Go to shop/play again/..." buttons? "hit/stand/etc" buttons are displayed right after you have received your two cards. For the "Go to shop/play again" buttons, I can make them available instantly instead of waiting for the results to finish yes :)
I think it would be nice to have some early exp(and maybe even money) upgrades that require money. Because as it stands now you don't care about your money at all in the early/mid game. It's all about getting exp by playing more hands - these allow you to get all the winnings/losing money upgrades and from then on you snowball to a billion.
I know that's partially a "ruining the game by optimising" problem but i still think there should be some more incentive to make money early.
