Not sure what it is but...
I'm not quite sure what the game is or anything but the graphics look pretty interesting. Kind of a mixing of styles from 2d to 3d. Maybe you have a follow up trailer that will explain more or give a bit of a demo as to what your game will be like.
I basically wanted to at least give you a review. The file size is huge admittedly but everyone deserves a review of some sort.
Good luck.
