Draw order messed up in Scene view.
Everything displays fine in game view and in game, but sprites that are clearly behind other sprites are often drawn on top in the Scene window.
Not really too big of a problem or anything, just did not see any mention of this in the forums.
If this is not a known bug, I can provide more info.
P.S. This could be a cool Fez like game idea, where things are drawn arbitrarily instead of based on their position in 3D space.
