Very great visuals, I really loved it! It really sets a nice mood.
On the other hand, the design felt a bit weak. I was able to cheese the game by spamming money on the training opponent to remove any randomness entirely and finish the game with just one dice. I would advise to add a turn limit to avoid cheesing and add more randomness on enemies to force players to consider bad outcomes in their strategies.
Everything else works very well though, so nice job!
