This is not a game, but a text file describing how to solve a game which sounds interesting - an old school text adventure with concepts from A Link to the Past - but which, ostensibly, doesn't actually exist in real life.
Or does it? Knowing Ryan Veeder, writing a walkthrough for a fake game is definitely something he would do. But putting a game in that text, or even making an entire text adventure game that you can only find by solving a puzzle in a text, is also something he would do. So I'm not sure. I'm not smart enough to know if this text is a game.
But as someone who wrote a lengthy GameFAQs walkthrough for a Mega Man game as a kid, with a lot of "now fall down the only chute to the right" and "shoot the enemy that appears", the genre of prose in this possibly non-interactive fiction appeals to me nonetheless.
