“I have no Walkthrough, and I must play. This game is great if you dont look at it as a game and more of a visual novel. the voice acting is superb (harlan Ellison has me screaming and drooling everytime he says…”
“Some of the puzzles can be really tedious but overall the story and voice acting are amazing and expand really well on the original short story”

“a old yet beautiful game inspired by a even older but wonderful book. what's not to love??”
“Love the art. Love the story. The gameplay... well... it's an old point-and-click adventure game. Unless you like clicking on the same objects again and again just in case something you just did triggered a new…”

“Fantastic game with a fantastic plot. Bugs are so common and so gamebreaking that this is not worth your money and debatable on if its worth your time. The story is something everyone should experience, but its very…”
“This is not a perfect game by any means, not only with the logic of a 1995 dos point and click adventure game but also with occasionally shoddy programming, but if you can allow yourself to look past that, you will find…”
