Great idea, and it has some potential!
But, to be honest, I don't think the "light" and "power" add anything here - it just makes things more confusing. Make it just about "dice-blackjack" - would be better, I think, and easier to understand. Also the controls with keyboard are quite weird given that most of the mechanics have no movement aspect and using mouse would be much easier.
Also nice visuals, but again - they don't quite fit the game, and would require some elaboration on what's going on.
But overall - nice submission! I enjoyed winning a few times :) And kudos for using Godot! :)
