So, I tried the demo this weekend and wasn't particularly impressed. The art is clean & whimsical ( in keeping with the Mana series ) but the frame rate feels choppy even on performance mode. I found the camera, FOV and controls "clunky" and a bit constraining. Combat doesn't have the same fluidity as in Granblue. In fact, this demo feels like a lower budget version of that game.
Overall, it's not a bad game, but I don't think I'll be picking it up especially with the likes of Space Marines 2, Black Myth : Wukong, Metaphor : Refantazio, Indiana Jones and the new Zelda game on the horizon. Can't see this being a massive commercial success for SquareENIX.
