Shadowforge 1.6.5
Fixed the Sprite Mask, when you press "F" and print the canvas it will be big as your sprite scale. Works with the Square and probably the Circle sprite, which start at 64x64. Not sure about the big circles, I have not tested it yet.
Changed the palettes. I think this was what corrupted the project (since when I resurrected it, it was not the same).
The palettes are now portrayed the way that GMS2.3 want it to work. Obviously, I am waiting for an update where they will fix it so that not everything is lighter when you change the alpha, but that you can code it however you want the alpha to turn into. But who knows if and when they will do something about that.
