So I finished the manga...and I really doubt they COULD even closely follow the plot... hell... there were such scenes, that only anime and manga can provide...
Well, it's apparent, that they made the game seem something like Liar Game, as creating the God of time, space and whatever would be a pain in the arse, not talking about MuruMuru... :p
And, God... Are they going to use the same powers for the users as in the mange, cause it would look totally badass!!! But... fat chance, right?
And the ending of the manga??? I was ok with it before the hammer appeared...pfft...
Yuno~creepy...
But the mangaka really thought out the plot, cause it was really interesting to read, until I got confused between the parallel worlds...
