玩法说明HOW TO PLAY

• 拖动场景中的光源，改变影子的大小与方向 Drag the light source to change each shadow's size and direction.
• 让墙上影子与蓝色轮廓重合，全部对齐即可过关 Align every shadow with its blue outline to clear the level.
• 点光源：越近影子越大；平行光：拖动改变光线角度 Point light: closer means bigger. Parallel light: drag to rotate rays.
• 灯放在物品之间，影子会分别投向左右两面墙 Place the lamp between objects to cast shadows onto both walls.
• 每关均有限时；提示共 3 次，范围会一次比一次精确 Each level is timed. Three hints — each one narrows the target zone.
