Great Concept Skillfully Delivered
Pro: new spells, cool monsters.
Con: no ending, multiple ties, short, mostly random interactions (so not much for the player to do except repeatedly press "roll").
Suggestions: more MP (so the player can use their spells through a 30-round encounter), ability to repeat fights in order to level up stats, more dice-tampering abilities (so as to add an element of strategy), how about each die against each enemy die?
Review: While the dice-rolling is random, certain powers (+2 and re-rolling) shift the odds enough in the players favor that the player can beat the dungeon. It's a cool idea, skillfully delivered, and it could certainly be taken to another level in its next incarnation. Great job!
