One day I wanted to come over and play the Microsoft Edge Surfing game (URL: edge://surf), but when I opened it, I found that the background had become water. Although the gameplay is the same, I think it is weird because the background is water. Maybe for some reason I think the background of the snow is a little better, and after it turns into water, it looks like a bit unaccustomed... (Maybe it's because of those frames)
I don't know if there are settings that change the background back to snow (maybe HTML?), but I still want to change the background back to snow. I hope not to programming, I suggest adding: use the "Settings" (gear) button in the upper right corner to directly change the background back to snow. (Or remove those frames but keep the water background)
