Hi! Thanks for this amazing project, it is really usefull!
I'm using it on Unity 5.5.0b6 and when I add GreyGuy to my project, the player asset doesn't have the references of the sprites and unity set my images as Textuye Type=Default instead of Sprite 2D.
I don't know what i'm doing wrong.
EDIT: I fixed it by selecting the sprites manually on the player.asset. Is there a way to select them manually?
