This was a mammoth effort by 80+ authors and programmers organized by Ryan Veeder and Jenni Polodna to celebrate the 20th anniversary of the classic work of horror interactive fiction "Anchorhead" by Michael Gentry.
It was written in "Exquisite Corpse" style where each author was unaware of the details of other author's contributions, with Ryan and Jenni providing the interfaces between different rooms. It thus varies wildly in style, tone, and feel; individual rooms can be story-focused, puzzle-focused, or somewhere in between.
The whole is a gigantic work that is puzzle-dense and which will alternately delight, amuse, confound, and horrify. Do not expect to jump in and finish it in an afternoon; it's taken weeks for contributing authors just to find their individual rooms during pre-release testing and debugging.
