The game is really well-made and fun to play. Both the blackjack and the Russian roulette parts work perfectly. As for the artistic side, I think the music fits really well, though I wasn't entirely convinced by the mix of visual styles.
The only issue I see is with the whole jam theme, which feels a bit forced. I guess "balancing risk" is essentially balancing, but it feels like stretching for a deeper meaning that isn’t really there.
Anyway, congratulations! I think you’ve created a really solid game.
P.S. This might be just me not getting the reference, but I found it a bit confusing that the red bullets are called 'live'.
