It should still be up, link still works for me (for the 0.1.0 version), as well as from my creator page.
As far as references, I tried to hint at the "real" games in the first "on pickup" messages for each game. So, for example, "Sleuth by Eric N Miller" becomes "Shamus by Erik 'Sleuth' Niller."

"Zill by Lynder and Edwyrds" is "Zyll by Linder and Edwards."

"Textventure Toolkit by Davis Mumberg" is "The Adventure Game Toolkit by David Malmberg."

"Copious Cavern Crusade by Woodther & Crows" is "Colossal Cave Adventure by Crowther and Woods."

"Hunt the Wompus by Grigori Yobb" is "Hunt the Wumpus by Gregory Yob."

"Softpron Adventure from In-Line Systems" is "Softporn Adventure from On-Line Systems."

"The Rook courtesy of Magnetized Scroll"  is "The Pawn, by Magnetic Scrolls." (The game as well is found in a Thieves' Guild, a reference to Magnetic Scrolls' followup game The Guild of Thieves, also "Rook" being another word for swindler/thief, which is a pun so weak I felt need to mention it explicitly here)

"The Galactic Stowaway's Manual by Adam Douglass" is, naturally, "The Hitchhiker's Guide to the Galaxy by Douglas Adams." (with special appearance by Marvin as 'Martin,' and Floyd from Planetfall as 'Lloyd.')

"Artie Bryanmorrie's Wishgetter" is "Brian Moriarty's Wishbringer."

And, of course, "Zurk: The Underground Umpire by Unfocom" is "Zork: The Great Underground Empire by Infocom."
