Reception
Manga Bookshelf's Katherine Dacey lists Amnesia Labyrinth as the fifth worst manga of 2011. Anime News Network's Carlo Santos commends the manga with its "deceptive leads and clues" and "calm, down-to-earth portrayal of home and school". However, he criticizes that Kohane's use of "careful shading, clean linework" serves to hide the "slightly off-kilter character designs and stiff facial expressions." A later review by Santos commends the manga for its logic puzzles and its use of "long silences, where the things unsaid between characters make it far more intriguing than any dialogue could have." With regards to the art, Santos commends Kohane for "using lots of hatched lines and ominous shading to create a different era where a supernatural back-story adds new layers to the series" but criticizes him for being inconsistent "when it comes to basic character design and anatomy".

Mania's Matthew Warner commends the manga's artwork with "the artwork provided looks fantastic, and is definitely one of the book’s main draws. Character designs look solid and display emotion well (though there is one instance in which a character strips that looks a little off, for whatever reason). However, the real star is the backgrounds and environments throughout, which appear often and have something of a stylized, sketchy feel to them, and are usually quite complex." School Library Journal's Snow Wildsmith commends Kohane's sharp artwork "full of feral smiles and vulpine eyes." She recommends the manga to the fans of psychological manga such as After School Nightmare and Higurashi When They Cry. Dacey heavily pans the "source material; as writer Nagaru Tanigawa explains in the afterword to volume one, Amnesia Labyrinth was “based on a story that, while it didn’t have enough to become a full-fledged novel, had been kicking around in my head for years.” He admitted that he had to “dismantle” his original idea and “reinvent the characters”; small wonder that the published version was, by his own admission, filled with “lazy, phantom passages,” vestiges of an earlier story idea."
