Nice art! It's a different take on the whole "death loop" that seems to be very popular this jam, so I like it. The game mechanics itself is quite simple, since it's based on Blackjack, a popular game on its own right, but the added cheats system makes it feel fresh. Music is somewhat too chill for the settings. Not bad by any means, but I thought it was a bit uninspired.
On the gameplay itself, I thought it was kinda weird that once you got to a few rounds, when you die, it's game over and you immediately get sent back to the beginning. Seems truly it's hell to try and get to 666 levels, lol
