FLOOBY (love the acronym) is an unreconstructed old-school treasure hunt. The author explains in the ABOUT text that he and a friend began work on it in 1983, but never managed to get it done. As of this writing, it's still not finished: this is a 2010 IntroComp entry.
The gameplay is pretty much what you'd expect: enter the house, find the secret passage to the Zork-like fantasy setting, outwit or overcome some mythical creatures, and take their stuff. Most of the puzzles are straightforward and some are familiar from literature and other games. Indeed, there's one ported wholly (every detail intact) from the original Adventure. It's probably meant as a good-faith homage, but without any sort of original spin or subversion, treads over into aping territory. I was able to get all 60 points, but couldn't get a final reply (To be continued, Thanks for playing, etc.). I'm not sure if there is one.
The author acknowledges that the appeal of this sort of game has diminished over the years, and he's not wrong, but I think he's selling the potential of his game short. I still enjoy old-school treasure hunts from time to time, and I imagine a lot of people do, provided that they're innovative and well-written. As tight as the memory requirements were back in the day, Crowther and Woods and Blank and Lebling managed to draw some pretty evocative scenes. FLOOBY doesn't, at least not yet. An old-school game can also be done with a modern sensibility, without being tongue-in-cheek and without losing any of the appeal of the classics. (See Emily Short's flawless Savoir-Faire). We've had 35 years now to learn what players find entertaining and what they don't (mazes!). There's no reason the author can't make a version of FLOOBY that stays true to his teenaged vision, while still benefiting from decades of progress in the form. My advice to him: don't just finish the game you were making in 1983. Make the 2010 version of the game you wanted to write in 1983.
