《離火長明2》（Nocturnal 2）是由Sunnyside Games製作，預計於2025年在Steam平台發行的2D橫向卷軸動作遊戲，支援繁體及簡體中文。延續前作背景，主角持有火焰聖劍，進入被神秘迷霧籠罩、逐漸毀滅的廢墟城市Ytash。必須維持火焰不滅，藉由點燃城市的機關來驅散迷霧，探索城市深淵並將火焰傳播到各個地區。核心機制圍繞火焰，故事逐步揭露城市的秘密，帶出重生的希望。

操作方面，強調快節奏的連擊與靈活的跳躍技巧，火焰聖劍不僅是攻擊武器，也用於點燃關鍵機關和火把。需善用道具與火焰寶石來強化技能或開啟新咒術，面對多種環境陷阱和強力Boss挑戰。遊戲結合平台跳躍與動作戰鬥，考驗對節奏與方向的掌握。畫面採用精緻的手繪2D動畫，利用細膩的光影效果呈現出迷霧與火焰交織的神秘氛圍，地圖設計屬於非線性Metroidvania風格，既具挑戰性又不顯冗長。

在市場評價上，前作《離火長明》在Steam獲得高度好評，玩家讚賞其創新的火焰玩法和爽快的戰鬥節奏，畫面風格也被視為近年來最美的2D動作遊戲之一。部分玩家認為遊戲偏短，主線約三小時，但在探索與挑戰方面深度十足。對於即將推出的續作，玩家與媒體普遍期待它能延續前作的優點，並在地圖探索、火焰系統及劇情深度上有所突破。

總結而言，《離火長明2》以火焰聖劍為核心特色，成功結合快節奏動作與豐富的視覺表現，打造出兼具美感與技術挑戰的遊戲。前作累積的良好口碑為續作奠定基礎，若能在原有基礎上加入更多內容與變化，有望成為動作平台遊戲的新經典。

Nocturnal 2 is a 2D side-scrolling action game developed by Sunnyside Games, slated for release on Steam in 2025. The game will support both Traditional and Simplified Chinese. Building on the narrative of its predecessor, players once again take up the Flame Sword, journeying into the crumbling ruins of Ytash, a city shrouded in a mysterious mist and on the brink of destruction. To survive and advance, players must keep the sacred flame alive, lighting mechanisms across the city to repel the encroaching darkness, uncover the depths of the ruined metropolis, and spread the fire to distant zones. The gameplay revolves around this fire-based mechanic, gradually revealing secrets hidden within the city and offering a glimmer of hope for its rebirth.

The controls are designed to emphasize fast-paced combo combat and agile traversal. The Flame Sword serves as both a primary weapon and a vital tool for igniting key switches and torches throughout the map. Players must make strategic use of consumable items and Flame Crystals to enhance abilities or unlock new fire-based spells. The game pits players against environmental hazards and challenging bosses, blending platforming elements with dynamic action sequences. The visual presentation is defined by hand-drawn 2D animations and refined lighting effects that capture the eerie interplay between mist and flame. The non-linear, Metroidvania-inspired level design offers exploration without overwhelming repetition, maintaining a strong sense of progression and discovery.

In terms of market reception, the original Nocturnal was met with strong praise on Steam, with players highlighting its innovative fire mechanics, satisfying combat flow, and striking 2D aesthetics. While some felt the main storyline was on the shorter side—lasting around three hours—the game’s depth in exploration and optional challenges provided significant replay value. With Nocturnal 2, both players and critics are anticipating a continuation of the series’ strengths, especially improvements in world-building, fire mechanics, and narrative depth.

In conclusion, Nocturnal 2 centers on the mystical Flame Sword, successfully blending high-speed action with rich visual storytelling. The game’s hand-drawn artistry, thoughtful gameplay mechanics, and expanding lore offer a compelling mix of beauty and challenge. Thanks to the positive legacy of its predecessor, this sequel stands poised to become a modern classic within the action-platformer genre—especially if it can build upon its foundations with more varied content and deeper gameplay systems.
