Appealing at first, but it quickly becomes repetitive...

...And its as shallow as a casual social game such as Zyngas and the like; the only strategy is also the only gameplay, and it consists in how many dices to roll... and its that ever and ever. There is no character building strategy, no equipment (besides dices which are limited in number, variety and interest), not many status effects hence no related strategy. So far from any RPG.
Since this game is published by Kongregate I expected a good soft core game, but this one is not more than a classic casual freemium with a theme and visuals able to attract (and unfortunately fool) soft core and indie games players.
