I didn't read reviews on this game before playing it so I expected an experience more like Bronze and less like Galatea - when in fact the reverse is true. As others have written, the majority of the game is asking questions and piecing together the back story. I didn't feel like trying to find all 18 endings because the plot is rather dark, and I managed to find a very nice ending on my third play, so I stopped there.
The story was not that appealing to me (It is somewhat of a gruesome tale and I prefer games with tangible puzzles rather than question-asking, anyway). I would give this story 3 stars but for the sheer impressiveness of number of authors, complex plot, and intricate dialog system.
One hint: You can shorten your inputs. For example, if the dialog prompts you with "You could ask about ..." just type "ASK" and it will assume you are talking about the prompted question. Similarly, "You could ask about X or Y" allows you to type "ASK X" and it will answer you as expected. Be careful of the words... for example, "I had a lot of schooling" would have to be "ask schooling" and not "ask school". Once you get the hang of it, you don't have to type as much as you might think!
My favorite pun: (Spoiler - click to show)"Lilith fair"est of them all. Ha!
