This is a top-down 2D puzzle-shooter where players alternate between light and dark phases. In daylight, observe the environment and read clues; in darkness, monsters emerge and must be defeated with specific bullet combos. Use the left-side canvas to note clues and plan routes while controlling your character on the right. Success demands both keen observation and strategy.

这是一个俯视角2D解谜射击游戏。玩家在明暗两个阶段交替探索关卡：白天观察环境、阅读提示；黑夜中怪物出没，用特定弹幕组合击败它们。左侧画布用于记录线索、规划路线，右侧操控角色移动、射击与交互，通关需要观察力与策略的结合。

You can play this game as a single-player game where you play both phases, you can also play this in 2 players and each play a phase, the first player mark the canvas for the second player.

这个游戏可以单人全程通关，也可以两个人一起玩，第一个人在画板上画完第二个人扮演第二个角色。
