《精靈情緣/失憶症 世界》（アムネシア ワールド/AMNESIA World）是由日本知名女性向遊戲開發公司Idea Factory旗下的乙女遊戲品牌Otomate所製作的戀愛冒險遊戲，對應平台為Nintendo Switch。最早於2014年在PlayStation Vita平台推出，屬於《AMNESIA》系列的衍生作，而Switch版本則為其後續移植，讓更多現代玩家能接觸這款人氣作品。

最大特色在於其世界觀與結構設計。不同於本傳《AMNESIA》的嚴肅與懸疑氣氛，《World》版本採用更加輕鬆、歡樂甚至帶有些許惡搞元素的風格。設定為平行世界系統，在多個不同風格的平行宇宙中體驗與各位攻略角色的全新互動故事，每個世界都有獨立的劇情走向與互動方式，使得整體內容更加豐富多樣。

主要的平行世界：「學園世界」、「音樂世界」、「犯罪懸疑世界」、。在每一個世界中，原本《AMNESIA》中的主角們會以不同的身分與背景登場，而玩家所扮演的無名女主角也會以對應世界的角色身份與他們互動，展開戀愛故事。這樣的設定讓原先已熟悉本傳劇情的玩家能從新視角重新認識這些角色，而對於初次接觸的玩家來說也能在相對輕鬆的氣氛中進入世界觀。

在操作方面，基本承襲乙女遊戲傳統的點選式冒險玩法。透過閱讀劇情、選擇對話與行動選項來左右劇情發展，觸發不同的事件與結局。Switch版本操作簡單直觀，無論是使用Joy-Con還是手持模式皆支援良好，並針對主機畫面與操作介面做優化，讓玩家可以輕鬆沉浸在各種戀愛與互動之中。此外，加入迷你遊戲與小挑戰，為整體流程增添趣味性與變化性，讓遊戲不僅僅是閱讀劇情，也具備一定程度的參與互動感。

在美術與配音方面，作為Otomate出品的作品，維持一貫的高水準。角色立繪細膩，風格延續系列美型浪漫的路線，背景場景也配合各平行世界的主題進行設計，呈現出風格鮮明且富想像力的視覺體驗。聲優陣容豪華，包括柿原徹也、谷山紀章、石田彰、宮田幸季等人氣男性聲優，皆再次回歸為各角色獻聲，極大提升角色魅力與情感張力。

至於市場評價方面，整體反響屬於中上，尤其受到系列粉絲與乙女遊戲愛好者的支持。玩家普遍肯定本作相較本傳輕鬆愉快、內容多元，能夠更自由地與喜愛的角色互動，加上多個不同風格世界的設定也為角色塑造帶來新鮮感。然而，也有部分評論指出，由於為衍生作，劇情深度與主線張力不如本傳強烈，更多是以「日常互動補完」的形式存在，對非粉絲或重劇情玩家來說可能吸引力略遜。

總結而言，《精靈情緣 世界》是獻給《AMNESIA》系列愛好者的溫馨互動作品。不僅延續系列角色的魅力，更透過平行世界的多重構想拓展角色關係的可能性。對於喜歡戀愛冒險遊戲的玩家來說，提供溫柔、幽默且充滿幻想色彩的戀愛體驗，若曾經喜愛系列中的任一角色或設定，那麼這款作品無疑是不可錯過的補完之作。

Amnesia: World (Japanese: アムネシア ワールド), is a romance adventure game developed by Otomate, the otome game brand under the renowned Japanese company Idea Factory. Originally released for the PlayStation Vita in 2014, this title is a spin-off of the AMNESIA series. The Nintendo Switch version is a later port that brings this popular game to modern audiences.

The game’s most distinctive feature lies in its world structure and setting. Unlike the main AMNESIA title, which is known for its serious and suspenseful tone, AMNESIA World adopts a lighter, more humorous, and sometimes even parodic style. The premise is based on a parallel world system, allowing players to explore a variety of alternate universes—each with its own storylines and interactive dynamics with the love interests. This structure adds significant variety and richness to the overall experience.

Key parallel worlds include the “School World,” “Music World,” and “Crime Suspense World,” among others. In each of these unique settings, the main characters from the original AMNESIA series appear with different identities and backgrounds, while the player, portraying the unnamed heroine, also takes on a role suited to that world. This gives returning fans a chance to rediscover familiar characters from new perspectives and offers newcomers an easy and enjoyable entry point into the AMNESIA universe.

In terms of gameplay, AMNESIA World retains the traditional point-and-click visual novel format familiar to otome fans. Players read through story text, make choices in dialogues and actions, and influence the branching narrative and multiple endings. The Nintendo Switch version offers intuitive controls, whether using Joy-Cons or in handheld mode, with interface and display optimizations that ensure a smooth, immersive experience. The game also includes mini-games and small challenges that add variety to the flow, providing a balance between story immersion and interactive engagement.

Visually and aurally, the game lives up to Otomate’s high production standards. The character illustrations are detailed and aesthetically appealing, maintaining the romantic and stylish art direction of the series. Backgrounds are uniquely tailored to each parallel world, delivering an imaginative and visually distinct experience. The voice cast is stellar, featuring popular male voice actors such as Tetsuya Kakihara, Kisho Taniyama, Akira Ishida, and Kouki Miyata, all reprising their roles from the original game, enhancing the emotional resonance and character charm.

In terms of reception, the game has been generally well-received, particularly among fans of the AMNESIA series and otome game enthusiasts. Players appreciate the more relaxed, diverse content compared to the main game, as well as the freedom to engage more deeply with their favorite characters. The concept of multiple themed worlds adds freshness and fun to character development. However, some critics note that as a spin-off, it lacks the narrative depth and dramatic tension of the original title, functioning more as a collection of daily-life side stories. For players seeking a heavy plot or unfamiliar with the series, the appeal may be more limited.

In summary, AMNESIA: World is a heartwarming and interactive spin-off created for fans of the AMNESIA franchise. It extends the appeal of beloved characters through imaginative parallel worlds and offers a charming, whimsical romance experience. For those who enjoy romance adventure games—or anyone who has ever been captivated by a character from the AMNESIA series—this is a delightful and worthwhile companion title.
