Hiya just a general question with the Pixel Game Maker Series, games.. Are they all like sample demos for the engine, or are the "Pixel Game Maker Series" games a separate thing just games made iwth the engine but would not be able to be loaded in Pixel Game Maker MV as a sample game to learn from it and so on?...
