The devil is damn good at his own game, but I am better. I don't know what were our bets, but I think that now I would be more worthy king of Hell than him.

Things that could be improved:

- add time limit of each turn

-the bigger the value of the  second card of the combo - the bigger the bonus

-make the music loop (cus it stops midgame)

Summary

      I think you should continue developing it. It could be very fun little game to play when you are tiered or want to kill some time.

     I play poker from time to time and that card game was pretty cool, I would love to see some new demons to go up against and maybe add particular abilities of each enemy(ex. switch one of your cards ) that would make the gameplay more enjoyable and will hold people's attention longer
