A really good concept. Using the real die instead of some ability die is really good, beacuse i can finally predict the sides of something. Although an isometric guide in the corner would still be welcome. The problem is with the balance. The die takes a lot of time to land, which wouldn't be a problem if the enemies weren't so fast. There isn't really time to shoot, even less to hink about what side to use. When you go fast, the die bounces a lot before it finally lands.
