Interested, but I have a few questions. 

Is this planned as more of a "mystery game," where the players will be encouraged to figure out who's doing this, why, and how?

Or will it be more of a "battle" scenario, where after using the power of the dice--perhaps to gain supernatural abilities or accomplish unlawful goals--players turn against each other and each must try to "win the game?"

Both are fine alone or as a hybrid, I just want to get a better feel for the atmosphere of the story so I can design my character accordingly.

It's intended as an open-ended sort of thing in that regard. If your character thinks that the influence of the dice is something to not be trusted, or to try and exploit or take control of, then they're more than welcome to try and figure out the system behind it, who "X" is, and the like. However, they should also consider that "X" might not take kindly to that. 

Similarly, if your character simply wants power, wants to survive, or wants to better themselves because of an inferiority complex, then it's probably in their best interests to just do quests and get more dice. There will likely be some PvP elements if you go down this route, depending on the specifics of what happens, but I don't want to get too in-depth on that because of spoilers.

But yeah, I won't tell you how to play the game, and I have things set up to where whatever choice you make, it's fine, so it entirely depends on personal preference.
