"It’s worth pursuing as it’s an interesting tale and a new take on the conventional gamebook format. Don’t be surprised if it makes one much more wary of fairgrounds in the future though!" - 148 Apps

"Graphic adventures like the excellent Monkey Island series and Simon the Sorcerer, as well as pioneers in interactive gamebook apps like the abovementioned Tin Man Games or inkle's Sorcery!, also served as inspirations." - Pocket Gamer

"The Sinister Fairground is well worth the investment when considering that there various paths to take through the story and also that each round requires multiple sessions. As I said before, I really found the game to be engaging." - Don't Forget a Towel
