Thank you for the review!
"World roll" is responsible for the choice of a world - Meadow/Snow world /Desert World.
"Princess Power" is responsible for the ability which the princess has: FIreball/Healing/Teleport/Increased Speed/Random skill.
Thus, the dices strongly affects the gameplay including what you can achieve and how and all the dices are meaningful.
I hope you have more clarify about the game now
