This is a game planned on an epic scale. Only 3 chapters were entered into the competition, and the author clearly promised greatness in those missing six chapters. There was to be an entire other complex (or multiple ones), many rooms, etc.
But even these chapters are unfinished in some ways. Many things are unimplemented. Trying to guess the right verbs can be hard even with the walkthrough.
It's also a bit offputting. Woman are all nude and described like meat. Murder is casual. I'm just not that into it.
