I was just making an enemy for Mari0 SE, and I required to use a .png image for the graphics of the enemy. So I made a Zombie Goomba image, and as soon as I save it as a PNG, the background fills up with whiteness again, I've saved this for what seems like a million times already, going back and forth making the image transparent again, and I just couldn't. So I need some help, please answer as soon as possible.
