Main feedback
The game has a genuinely great atmosphere that pulls you in right away. To make the gameplay as engaging, I’d suggest looking into a couple of points: the AI opponent plays quite predictably/weakly at the moment, and the repeated animations with pauses between actions can sometimes break the flow.
Separate note on the idea
I also wanted to say it’s really cool how you put your own spin on the classic “Liar’s Dice” / truth-or-bluff formula. The twist of using dice as both your betting tools and your health pool is a neat and impactful idea. It adds a fresh layer of tension to a well-known game.
