Oh, that's exactly the effect I want!!
cover_effect.gif
I want to implement a screen change in my game with this effect
Do you have any intention of making this cover_effect.gif as a sprite sheet?

Yes, I just needed one color. But it`s very easy to change the sprite sheet color with any kind of image or pixel editor. In case of a pixel editor, just use the the bucket tool (there are also online tools, such as this: https://www.piskelapp.com/ ). Have fun!
By the way, I put the files into a .zip file, called Cover_Smoke_Effect.zip, in order to organize things.
