Great take on the theme and really solid execution on your idea! I really like this game! What a fun way to battle, and I really like the tradeoffs of picking bad sides for your die in favor more gold.
One suggestion I have, is that it felt like I really had no influence with A and D (which I'm sure was intentional to be subtle). But it would be nice if there was even a small visual indicator so I knew I was doing something.
This was a wonderful game and very inventive. Congrats on submitting and thanks for the game!
