Echo Blind

 # Echo Blind / 回声盲境

  Echo Blind is a 2D puzzle platformer built around darkness, echoes, and limited perception.

  The player explores a nearly pitch-black world where platforms, traps, switches, coins, monsters, and hidden paths are

  invisible by default. To understand the environment, the player must emit different sound waves and briefly reveal parts of the world.

  Every echo has a cost. Sound can expose your position, reduce the value of coins, attract danger, or force you to make

  risky decisions with incomplete information.

  《回声盲境》是一款以“全黑环境 + 声波显形”为核心的 2D 横版解谜平台游戏。

  玩家处在几乎全黑的世界中，默认看不见道路、机关、金币、怪物和危险。你需要释放不同频率的声波，让隐藏在黑暗中的世界短暂显现出来。

  但每一次发声都有代价：声波可能消耗金币价值，可能惊动怪物，也可能让你暴露在危险之中。
