Your game is incredible especially for a game jam. It’s polished, well-made, and has great length; I honestly have nothing bad to say. Bravo. The only thing is, I don't really see the horror aspect in it.

This is pretty cool, i love all the small polish game feel juice! Good job I love blackjack so i loved it, also you should check out my game!

Awesome!
I'd play the full game.
Having a table where you could see the enemy's hands or some other visual aid would help a lot in terms of immersion.
