In order to get A you need to NOT wait too many years, otherwise the arrow at the beginning of the maze will turn red. (it has to stay green) I completed it with like 70 - 75 dice, so it's doable. To get B you have to die many times so the arrow at the beginning turns yellow. Strategy: the guardian gives you 5 dice for each time you die so you can use them to lose on purpose right at the start, then you can get dice by waiting but be careful cuz the arrow will turn red if you wait more than 60 years (I think).
