Amnesia World

Amnesia is an otome game; the player takes the role of a female character who can choose from a variety of male characters for her love interest.

In Amnesia, the male characters that the female character can interact with are based on the symbolic suit symbols from a card deck with the following storylines, commonly known as routes: Heart, Spade, Clover, Diamond and Joker. The player's relationship with each character differs depending on which route is chosen. Each route is a parallel world where the heroine seeks to understand more about her selected male character.

The anime adaptation of Amnesia was generally poorly received. Anime News Network's Rebecca Silverman gave the first half a C grade overall, commenting "Parts of it are fascinating...while other parts are intensely annoying", and said the show "basically feels like watching someone else play the game." Matthew Lee, writing for Twitch Film, opined that Amnesia's "story offers nothing of any interest beyond the burning question of what the hell any of it means." Seb Reid of UK Anime Network rated it 4 out of 10 and called it "A show that is best forgotten." Silverman gave the second half an overall grade of D, saying that "Ultimately Amnesia ends as it began – fascinating in the same way a loose tooth is, but the payout when you finally get rid of it doesn't feel like enough."
