I've seen about 4 peoples reaction who played it, all said it was beautifull also all 4 said it was "the worst running game ever on the ps4 system" and had dated controlls. the story is supposedly quite good and the puzzels fun.
I think the reviews will be mixed because priority on the good and bad points are going to be mixed.
So I assume it will score around the 75 with some praising its unqiue artstyle and graphics and others pointing out the flaws.
I think this game would have been a great one for the "40 dollar" price tag like they did with ratchet and clank, it would proberbly score higher then
