殘響協定

《殘響協定》是一款像素風2D橫向捲軸動作遊戲，背景設定在2511年。人類意識雲端化追求永生，卻衍生出巨型企業與宗教的壓迫。玩家化身輔助智能機Echo，協助改造少女靜羽與便利屋《V.E.I.L.》成員，逃離掌控，在廢墟都市與異變地帶展開諜影任務。透過橫向探索、互動解謎與任務系統，調查「彼岸因子」與「冥王制壞」的核心真相。
核心玩法以節奏判定戰鬥為最大特色：戰鬥時出現節奏條，精準命中perfect可達2倍傷害，bad僅0.5倍。超載模式下全域攻擊固定2倍傷害，但結束後靜音10秒並無法充能。玩家可自訂殘響模組與紅/藍/紫/黃/特殊數據芯片，改變攻擊倍率、子彈效果與數值。結合平台跳躍、移動平台機關與芯片升級系統，打造爽快戰鬥與策略深度。
故事透過靜羽的多重時間線與殘缺記憶碎片，引導玩家逐步拼湊真相，並解鎖多結局。遊戲傳達「即使破碎也能前行」的深刻共鳴，讓玩家在推理與情感交織中，體驗人性、身份與反抗的重量。
