Great game btw, loving it and hoping you make your sequels, something I did notice however was a Demon's Deal Exploit that may or may not be intentional.

It appears you can still proceed with a hand despite not having enough money to bet.

So if the minimum bet is 15, and you have 12, and you choose "bet 15" it will tell you that you don't have enough but the pot still increases by your opponent's bet. This allows you to easily win a single big hand if you are low on money, so it's not able to be abused unless you are low on money. It may be intentional bc otherwise you would have to have a minimum of the maximum total possible bets over every round available at the beginning of the game to cover all possible bets, which I believe would be 100.

Not sure if that makes sense, but that's the deal with Demon's Deal.
