Although the graphics engine looks nice and the physics engine "feels" OK, there are by far too few ways to configure the used dice. For example, my default use case requires two differently colored D10, which you simply cannot configure. Alternatively, Id use one D100, but alas, this isnt available as well. What about using more than six D6? No way. If the developers provided more freedom in configuring the number, shape and color of the dices, Id add the fourth star. If the developers allowed to save such configured "sets" of dice, Id add the fifth star.
