I can relate to this.
The reason being that I have {A} sort of done this before and {B} have seen the worlds behind the completed article. It's a foreign land back there, with countless strangeness to explore. This one is relatively simple, but it can apply to all things. Every break of a game, every loophole and every glitch is a pathway into a secret world underneath the game. In many ways, they can be as interesting as the game itself.
This reminds me of everything from the Underworld of Legend of Zelda: Link's Awakening to one of the empyrical POINTS of the Dot-Hack series. And yet, what this really reminds me of, in essence, is Adventure, that old Atari game. The maker of the game was not allowed to take credit for his world, but deep within it, behind the game itself in his secret world...you could find him.
That's what all this game makes me think of, and I like the way it takes it.
