《月風魔傳：不朽之月》（GetsuFumaDen: Undying Moon）是由Konami與GuruGuru共同開發的2D橫向動作遊戲，2022年2月17日於Nintendo Switch平台正式發售。作為1987年在Famicom上推出的《月風魔傳》的精神續作，以完全重製的形式重現舊作的世界觀與角色設定，並融合現代roguelite與魂系遊戲的要素，打造出風格強烈的和風暗黑動作遊戲。

劇情背景設定在一個由妖魔與神靈並存的古代日本世界。主角是月氏一族的繼承者「月風魔」，作為負責鎮守地獄之門的劍士，肩負封印從冥界蘇醒的妖魔之王「龍骨鬼」的任務。前任族長在封印戰中犧牲後，月風魔挺身而出，獨自深入被妖魔侵蝕的地獄，踏上穿越九重冥界的試煉之旅。隨著深入探索，將逐漸揭開冥界異變的真相，以及月氏家族與冥界之間的宿命關係。儘管劇情簡潔並非以對話推動，但透過場景中的圖騰、日記與敵人造型，逐漸勾勒出一個充滿東方陰森氣氛的世界。

在操作與系統方面，以高速的橫向動作為主，融合動作遊戲與roguelite隨機要素。每次挑戰地獄關卡時，地圖結構、道具配置、敵人分布都會不同，死亡後需從最初關卡重新挑戰，具有高重玩性與策略思考空間。戰鬥方面，可裝備近戰武器如太刀、大劍、長槍，以及遠程武器如弓箭、手裡劍等，並可攜帶兩套武器在戰鬥中隨時切換。每種武器不僅手感不同，還具有專屬技能與屬性攻擊，例如燃燒、毒素或震退效果，可依照敵人特性進行戰術調整。閃避與防禦時機極為關鍵，敵人的攻擊模式多變，有些Boss更具備類魂系的強力招式，要善用閃避與破綻反擊。

畫面是一大特色，以濃厚的浮世繪風格結合水墨筆觸呈現地獄與妖魔的場景與角色，整體畫面猶如一幅幅動態的古畫，視覺衝擊感極強。場景橫跨鬼火森林、血海神殿、骨塔迷宮等多重地獄層次，每個地區都有截然不同的美術與敵人設計，營造出詭譎而詩意的陰界氛圍。配樂則採用融合和樂器與電子元素的方式，加深東方奇幻的沉浸感，營造出如夢似幻的戰場氣氛。

在養成系統方面，可在探索過程中獲得各類資源與「魂片」，用來在基地中解鎖角色強化、武器製作與技能升級。透過這些元素，即便每次挑戰都從頭開始，但角色與裝備會逐步成長，提供長期進度感。也設有可調整難度的「試煉模式」與「煉獄難度」，對於動作遊戲老手而言具備極高挑戰性與耐玩度。

就市場評價而言，在Switch平台上獲得玩家普遍正面評價。許多評論指出，其獨特的和風美術風格與流暢戰鬥設計是最大亮點，尤其是BOSS戰設計富有張力，令人回味無窮。IGN給予6.9分，稱讚遊戲畫面極具美術價值，戰鬥有深度但節奏偶有斷裂。GameSpot則評為6分，指出其roguelite元素雖富挑戰性，但內容重複度稍高，若能增加更多事件與分支將更豐富。此外，有部分玩家提及，遊戲在初期版本存在一些操作延遲與UI不友善的問題，但後續更新已逐步改善。

整體而言，《月風魔傳：不朽之月》融合傳統與創新，透過動作與隨機要素交織，打造出兼具藝術性與挑戰性的遊玩體驗。無論是喜愛浮世繪風格、東洋妖怪題材，還是熱衷魂系與roguelite類型的玩家，這款遊戲都值得一試。

GetsuFumaDen: Undying Moon is a 2D side-scrolling action game co-developed by Konami and GuruGuru, officially released on the Nintendo Switch platform on February 17, 2022. As a spiritual successor to the original Getsu Fūma Den launched on the Famicom in 1987, this reimagined title rebuilds the classic’s setting and character framework from the ground up, while integrating modern roguelite and Souls-like gameplay elements to deliver a striking, Japanese-style dark fantasy experience.

The game’s narrative is set in an ancient Japanese world where demons and deities coexist. The protagonist, Getsu Fuma, is the heir of the Getsu clan and a swordsman tasked with guarding the gates of Hell. After the former clan leader falls in battle while sealing the demonic overlord Ryukotsuki, Fuma rises to face the threat alone. He ventures deep into the corrupted Netherworld, undertaking a trial through its nine layers to uncover the source of the infernal unrest and the long-standing connection between his bloodline and the underworld. Although the story unfolds without much dialogue, the worldbuilding is richly conveyed through totems, scattered journals, and the eerie design of enemies, gradually painting a haunting yet poetic vision of the netherworld.

Gameplay centers around fast-paced side-scrolling combat, enriched by roguelite mechanics that ensure each descent into Hell offers a different experience. Maps, item placements, and enemy encounters are randomized, and death means restarting from the beginning, giving the game high replay value and strategic depth. Players can equip two sets of weapons — including melee tools like katanas, greatswords, and spears, as well as ranged options like bows and shuriken — and switch between them freely in combat. Each weapon has a distinct feel and may possess unique skills or elemental effects such as fire, poison, or knockback, allowing for tailored tactical approaches depending on enemy types. Timing dodges and blocks is essential, especially in challenging boss fights that draw heavily from Souls-like design with punishing patterns and small attack windows.

One of the game’s most celebrated features is its visual presentation. The art style is a bold fusion of ukiyo-e aesthetics and ink-brush strokes, turning each environment into a living Japanese painting. From ghost-lit forests to blood-drenched temples and skeletal labyrinths, each stage offers distinct visuals and enemy designs, establishing a surreal and atmospheric world. The soundtrack blends traditional Japanese instruments with electronic tones, enhancing the game’s fantastical tone and making each battle feel like a mystical dreamscape.

The progression system is structured around collecting resources and "soul fragments" during exploration. These are used to unlock character upgrades, forge new weapons, and enhance skills back at the base. Although each new run starts from scratch, long-term progress is achieved through persistent upgrades. The game also includes a Trial Mode and Hell Difficulty, offering significant challenge and replayability for seasoned action gamers.

In terms of market reception, GetsuFumaDen: Undying Moon received generally positive feedback on the Switch. Critics and players alike praised its unique visual identity and responsive combat mechanics. Boss battles were particularly highlighted for their intensity and design. IGN gave it a 6.9, commending its artistic value and combat depth but noted some pacing inconsistencies. GameSpot rated it a 6, appreciating its difficulty and roguelite systems but criticizing repetitive content and a lack of variety in events and branching paths. Some early complaints pointed to input lag and a less intuitive UI, though these were largely addressed through updates.

In summary, GetsuFumaDen: Undying Moon successfully marries traditional Japanese aesthetics with modern game design, delivering a visually stunning and mechanically engaging experience. Whether you're drawn to ukiyo-e visuals, Eastern mythology, or enjoy challenging roguelite and Souls-like mechanics, this title offers a uniquely stylized journey worth exploring.
