Last Dungeon Dice

Players can activate their skills with dice, attack adventurers, and repel adventurers by doing enough damage.
The repulsed adventurers can be turned into crystals or scouted to serve as allies.
Dungeon is filled with magical energy called Mana, but Mana is lost every time an adventurer fails to repel her.
When all the manas are gone, the magic of sealing the deepest princess's door is released.
If the adventurer cannot be repelled and the princess at the back of the dungeon is recaptured, the player will lose.
Can you fight off all adventurers and prevent Princess from recapturing them while recovering various events, items, and dungeon mana?
