B&W 1024*1024:

The first four icons are common icons.

Because My app has two parts of the content, the first is the background story of the game, and the second is the strategy of the game. So I made another two icons for them. The fifth icon means the story. The Sixth icon means strategy.

(I use photopea to vectorize my icons)

About the color: Currently, I am going to use the website background blue as my icon color. I will adjust it when making the real project.
