Superb Blackjack!
This game is Blackjack done right. The sound is uncommon (scissors-like on the deal) but not bad. I played many rounds and did not tire of the sounds very much. The graphics are excellent, so no improvements required there. The gameplay is easy-to-use Blackjack - enough said. If you are planning on revising anything, you don't need to repair the game - but some (very easy to add) upgrades that you might consider for future versions would be menu selections for things like:
number of decks used per game and shuffle frequency
double on any first play
double on any play
no insurance
and similar game options in case you want to deviate a little from strict house rules...
Also, perhaps a table for selecting bet amounts that go in higher or lower increments so that it doesn't take as long to bet large amounts.
Still, this game is great - so those are only suggestions for future releases - I like this one as is!
