This game is really pretty and polished, and I enjoyed it. The balance wasn't very thought out, however. I can buy guaranteed D4s for 1 coin, which means I can roll on average a 2.5/coin. Even if I would get D20s every time I put 6 coins in (which isn't guaranteed), I would roll a value of 1.75/coin on average. And the optimal strategy doesn't even let you discover cool dice like the body die.
